The body of water that is found between Saudi Arabia and Iran and was a focus of both the Iran-Iraq War and the war following the invasion of Kuwait by Iraq in 1990 is the Persian Gulf.

Explanation:

The Persian Gulf is an extension of the Indian Ocean that separates Iran from the Arab countries such as Saudi Arabia. Other countries with a coast on the Gulf are Iraq, Kuwait, the United Arab Emirates, Qatar and Oman, while Bahrein is an island in the Gulf. Because much of the world's oil comes from this area, it is of exceptional strategic importance and many wars have been fought here. Apart from oil, the Persian Gulf is notable for its richness in fish and pearls, but has been somewhat damaged by the oil industry in recent years.

The area of the Gulf is about 233,000 km². On the east side the Hormuz Strait connects it to the Gulf of Oman. On the west side is the Shatt al-Arab, where the Euphrates River and the Tigris River reach the sea. It's not very deep, about 90 m. at the deepest point and about 50 m. on average.
