If you look at a globe and find that massive, boot-shaped block of land wedged right between Africa and the rest of Asia, you’re looking at the Arabian Peninsula. Honestly, it’s hard to miss. It sits in the extreme southwestern corner of Asia, acting like a giant bridge between continents. You’ve probably seen it a thousand times in history books or on the news, but actually pinning down its exact borders on a map can be a little tricky because it’s so huge—about 1.2 million square miles, to be specific.
That is roughly the size of the entire Indian subcontinent.
Basically, the peninsula is surrounded by water on almost every side, which is why it’s a peninsula in the first place. To the west, you have the Red Sea, which is that long, narrow strip of blue separating it from Africa. Down at the bottom, to the south and southeast, the land meets the Arabian Sea and the Gulf of Aden. Then, if you wrap around to the east and northeast, you hit the Persian Gulf (some people call it the Arabian Gulf) and the Gulf of Oman. It’s almost entirely encircled, except for the north where it just sort of bleeds into the Syrian Desert.
Where Is the Arabian Peninsula on the Map Exactly?
When you’re trying to find the "top" of the peninsula, things get a bit fuzzy. Unlike a coastline, which is a hard line, the northern boundary doesn't have a clear natural marker. Geographers usually just use the northern borders of Saudi Arabia and Kuwait to draw the line. If you want to get technical about it, parts of southern Iraq and Jordan also technically sit on the peninsula's landmass.
The coordinates usually hover around 25.0000° N, 45.0000° E.

Imagine a giant rectangle tilted slightly. The western side is lined with mountains—the Hejaz and Asir ranges—that drop off sharply into the Red Sea. On the other side, the land slopes down very gently toward the Persian Gulf. It’s like a massive, tilted tabletop covered in sand.
The Neighbors Next Door
The Arabian Peninsula isn't just one big empty space. It’s shared by seven main countries, though one of them is actually an island.
- Saudi Arabia: This is the big one. It takes up about 80% of the entire peninsula.
- Yemen: Located at the southwestern tip, where the mountains are highest and it actually rains sometimes.
- Oman: Occupies the southeastern corner, featuring a stunning coastline and the Hajar Mountains.
- United Arab Emirates (UAE): Perched on the eastern edge along the Persian Gulf.
- Kuwait: A small but wealthy spot at the very top of the Persian Gulf.
- Qatar: A thumb-shaped peninsula sticking out of the side of the main peninsula.
- Bahrain: An archipelago in the Persian Gulf, technically not "on" the landmass but always grouped with it geopolitically.
The Landscape: More Than Just Sand
People think "Arabian Peninsula" and immediately picture endless dunes. They aren't wrong, but it’s not the whole story. The Rub' al Khali, or the "Empty Quarter," is the star of the show here. It’s the largest continuous sand desert on Earth. It’s absolutely massive—covering about 250,000 square miles. To put that in perspective, you could fit all of France inside that one desert.
But then you have the mountains.

In the west, the Sarawat Mountains run parallel to the Red Sea. Some peaks here, especially in Yemen and southern Saudi Arabia, hit over 10,000 feet. It’s actually quite cool and green in some of these high-altitude spots. You’ll find ancient stone terraces where farmers have been growing coffee and fruit for centuries. It's a weird contrast to the scorching gravel plains just a few miles away.
Water and Wadis
There aren't any permanent rivers here. Not a single one.
Instead, the map is crisscrossed with "wadis." These are dry riverbeds that stay dusty for 360 days a year. But when a rare, heavy rain hits, they turn into raging torrents in minutes. It’s actually pretty dangerous if you’re camping in one. Most of the water people use comes from massive underground aquifers or, more commonly these days, from high-tech desalination plants along the coast.
Why This Spot Matters on the Global Map
The location of the Arabian Peninsula is one of the most strategic "real estate" spots on the planet. Think about the shipping lanes. On the west, you have the Suez Canal and the Bab-el-Mandeb strait. On the east, you have the Strait of Hormuz.

A huge chunk of the world’s oil and natural gas passes through these narrow bottlenecks every single day. If one of those straits gets blocked, the global economy basically has a heart attack. This is why you see so much international interest in the geography of the region. It’s not just about the land; it’s about the water surrounding it.
Historically, this was the "crossroads of the world." The incense trade routes started here, carrying frankincense and myrrh from the southern coast of Oman and Yemen up to the Mediterranean. It’s a place where the cultures of Africa, Asia, and Europe have been bumping into each other for thousands of years.
A Few Surprising Geographic Facts
Honestly, the more you look at the map of this place, the weirder it gets.
- It’s moving: The entire Arabian tectonic plate is slowly pulling away from Africa. That’s what created the Red Sea in the first place, and it’s still widening by about an inch every year.
- Volcanoes: Most people don't associate Saudi Arabia with volcanoes, but the western side is covered in "harras"—vast fields of black, solidified lava from volcanoes that were active just a few thousand years ago.
- The Farasan Islands: Off the southwest coast, there’s a cluster of coral islands that look more like the Maldives than a desert region.
Finding Your Way Around
If you’re planning to travel or just want to understand the region better, start by looking at the coastlines. The "Red Sea coast" is generally more mountainous and rugged. The "Gulf coast" is flatter, more industrial, and home to those futuristic skylines like Dubai and Doha. The "Southern coast" (Oman and Yemen) is where you find the most unique geography, including the Khareef monsoon in Salalah, which turns the desert bright green for a few months every year.
To get a real feel for where the Arabian Peninsula is on the map, don't just look for the sand. Look for the water boundaries. Once you see the Red Sea and the Persian Gulf framing that massive block of land, everything else falls into place.
Actionable Next Steps for Map Enthusiasts:
- Check a Satellite View: Open Google Earth and zoom into the "Empty Quarter" (Rub' al Khali). The patterns of the sand dunes from space are actually mind-blowing and look like orange waves.
- Trace the Tectonic Lines: Look at the "Afar Triangle" in Africa and see how the jig-saw puzzle of the Red Sea fits perfectly into the coast of the Arabian Peninsula.
- Explore the High Points: Search for Jabal Sawda in Saudi Arabia or Jabal Shams in Oman to see photos of the mountain ranges that defy the "all desert" stereotype.
