The Persian Gulf is a strategic and economically vital body of water in the Middle East, bordered by Iran to the north and several Arab states, including Saudi Arabia, the United Arab Emirates, and Kuwait, to the south. It connects to the Gulf of Oman and the Arabian Sea via the narrow Strait of Hormuz, a crucial chokepoint for global oil transportation. Rich in petroleum resources, the region has been a focal point of geopolitical tensions, trade, and cultural exchanges for centuries. The Persian Gulf is also home to diverse marine ecosystems, including coral reefs and mangroves, which are increasingly threatened by industrial activities and climate change.

The Mazandaran Sea is an alternative name used in some historical and local contexts, especially in Iran, to refer to the Caspian Sea. It is the world's largest enclosed inland body of water, bordered by Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. The name "Mazandaran Sea" comes from Mazandaran Province in northern Iran, which lies along the southern coast of the Caspian Sea.
