Walk into any VFW post or a Vietnamese-American neighborhood in Orange County, and you’ll see them. Different colors. Different meanings. Total opposites. When we talk about the flags of the Vietnam War, we aren't just talking about colored fabric or military heraldry. We are talking about the ghosts of a conflict that never really "ended" for the people who lived through it.
Most history books keep it simple. They show you the Stars and Stripes, the yellow flag with three red stripes, and maybe the red one with the gold star. But that’s barely scratching the surface of what was actually flying over the rice paddies and the streets of Saigon. Honestly, the visual landscape of that war was a chaotic mess of symbolism.
The stakes were high. Still are.
The Yellow Flag: More Than Just South Vietnam
For a lot of people, the "Heritage Flag"—the yellow field with three horizontal red stripes—is the most recognizable of the flags of the Vietnam War. It’s the flag of the Republic of Vietnam (RVN). You see it at memorials and Tet festivals today.
But where did it actually come from?
It wasn't some random design cooked up in 1955. It actually dates back much further, tracing its roots to the Emperor Thành Thái in 1890. The three red stripes represent the three regions of Vietnam: North, Central, and South. It was a bid for national unity long before the Americans ever showed up with helicopters and M16s. When Ngo Dinh Diem became president, this flag became the symbol of a non-communist Vietnam.
For the "Boat People" who fled after the fall of Saigon in 1975, this flag is everything. It represents a lost country. It’s a symbol of freedom from the regime they left behind. But if you fly this flag in modern-day Hanoi or Ho Chi Minh City? You’re asking for a very fast, very unpleasant visit from the police. It’s banned there. Totally illegal.
This creates a weird, lingering tension in international relations. Even recently, in places like Australia or California, local governments have gotten into heated debates about whether this flag can be flown at official events. It’s a piece of cloth that still has the power to start a riot or a diplomatic incident fifty years after the last US troops left.

The Red Flag with the Gold Star
On the other side, you had the flag of the Democratic Republic of Vietnam (DRV). This is the "Red Flag with the Gold Star" (Cờ đỏ sao vàng). It’s the official flag of Vietnam today.
The design is pretty straightforward. Red for revolution and the blood of the people. The five-pointed gold star represents the five main classes in Vietnamese society: intellectuals, peasants, workers, entrepreneurs, and soldiers. It was first used during an uprising against the French in 1940 and was later adopted by the Viet Minh.
During the war, this was the flag of "The North." To an American GI in the Highlands, seeing this flag meant you were in a "hot" zone. It was the banner of Ho Chi Minh.
The NLF Flag: The One That Confused Everyone
Then there’s the flag of the National Liberation Front (NLF), better known to Americans as the Viet Cong. This one is often confused with the North Vietnamese flag, but it’s distinct. It’s split horizontally: red on top, blue on the bottom, with that same gold star in the middle.
Why blue?
The NLF wanted to present themselves as a broad nationalist coalition, not just a communist puppet of the North. The blue was supposed to represent peace and the hope for a neutral South Vietnam. It was a psychological tool. It said, "We aren't the North, we're just Southerners who want the Americans out."
Of course, after 1975, that "neutrality" evaporated pretty quickly. The NLF was absorbed, and their flag basically disappeared from official use, replaced by the solid red flag of the unified Socialist Republic. It’s a bit of a historical footnote now, but during the 1960s, it was the primary symbol of the insurgency. You’d see it flying over captured villages or being waved by anti-war protesters in Berkeley and London who wanted to signal their support for the "liberation" movement.

Small Units and the "Beer Can" Patches
If you look at the flags of the Vietnam War from a boots-on-the-ground perspective, it gets even more granular. We can't ignore the guidons and unit flags.
American units carried their colors, but they also created an entire subculture of "theatre-made" flags and patches. Because the war was so decentralized, many platoons or Special Forces A-teams had their own unofficial banners. These were often made by local Vietnamese tailors in towns like Nha Trang or Da Nang. They used whatever silk or heavy cotton was available.
- The 1st Cavalry Division (Airmobile) had that iconic yellow shield with the black horse head.
- The 101st Airborne had the "Screaming Eagle."
- MACV-SOG (Military Assistance Command, Vietnam – Studies and Observations Group) had some of the most specialized, secretive iconography of the era.
These weren't just for show. In a jungle environment where communication broke down and "friendly fire" was a constant, terrifying reality, these symbols were identity. They were tribal.
The Controversy That Won't Die
Why are we still talking about this? Because the Vietnam War is one of the few conflicts where the "losing" side's flag still has a massive, active life in the diaspora.
In the United States, there are "Heritage Flag" ordinances in dozens of cities. In 2023 and 2024, we saw renewed debates in places like Westminster, California, about the display of the South Vietnamese flag alongside the US flag. For many Vietnamese-Americans, the red and gold flag of the current Vietnamese government is a symbol of oppression. They won't touch it.
Conversely, the Vietnamese government views the yellow flag as a "relic of a puppet state."
It’s a rare case where the physical objects of the war—the flags of the Vietnam War—continue to act as a primary flashpoint for political identity decades later. Most wars end, and the flags go into museums. Here, the flags are still out on the street. They still represent a divide that hasn't fully healed between those who stayed and those who left.

Specific Symbols You Might Encounter
If you are a collector or a history buff, you’ve got to be careful. The market for "original" Vietnam-era flags is flooded with fakes.
True period-correct NLF flags were often hand-sewn. They weren't mass-produced in a factory with perfect stitching. They were often made of thin, cheap parachute silk or whatever scraps could be scavenged. If you find a "Viet Cong flag" that looks like it came off a modern digital printer, it’s a souvenir, not a relic.
The US flags used in the field were also different. Because of the humidity and the rot, flags didn't last long. Many "casket flags" brought back by families are the most well-preserved examples, but the ones actually flown over firebases are often tattered, sun-bleached, and stained with the red dust of the Central Highlands.
What to Do With This Information
If you are researching this for a school project, a museum exhibit, or just personal interest, here is how you should handle it:
- Context is King: Never display the South Vietnamese flag and the current Socialist Republic flag together without expecting a reaction. To many, it's like putting fire and gasoline in the same room.
- Verify Provenance: If you're buying a historical flag, look for "theatre-made" characteristics. Look for uneven stitching and local fabrics. Authentic pieces usually have a story or "bring-back" paperwork from a veteran.
- Respect the Diaspora: Understand that for the Vietnamese-American community, the yellow flag with three red stripes isn't "the old flag"—it is their flag. Using the current official flag of Vietnam in these communities can be seen as a deep insult.
- Check Local Laws: If you're in Vietnam, don't carry or display the RVN flag. It is a criminal offense. Seriously.
The flags of the Vietnam War are more than just historical artifacts. They are living symbols of a struggle for identity, a reminder of a divided world, and a tribute to the millions of people—soldiers and civilians alike—who were caught in the middle of a Cold War firestorm.
To understand the flags is to understand that the war isn't just a chapter in a book. For millions of people, the war is still flying on a flagpole in their front yard. It's a way of saying "I am still here, and I remember." That kind of conviction doesn't just fade away with time. It stays bright, just like the colors on the silk.
If you want to see these in person, the best places aren't just the big national museums. Check out the Museum of the Republic of Vietnam in Westminster, California, or the various Vietnam Veterans Memorials scattered across the US. You'll see the real history there, written in thread and stripes.
Next time you see a yellow flag with three red stripes, don't just see a piece of history. See a bridge to a country that no longer exists on a map, but lives on in the hearts of the people who flew it. That is the real power of these banners. They outlasted the borders they were meant to define.
