The Gulf of Oman or Sea of Oman (Arabic: خليج عمان khalīj ʿumān; Persian: دریای عمان daryâ-ye omân), also known as Gulf of Makran or Sea of Makran (Arabic: خلیج مکران khalīj makrān; Persian: دریای مکران daryâ-ye makrān), is a gulf that connects the Arabian Sea with the Strait of Hormuz, which then runs to the Persian Gulf. It borders Iran and Pakistan on the north, Oman on the south, and the United Arab Emirates on the west.

The Gulf of Oman historically and geographically has been referred to with different names by Arabian, Iranian, Indian, Pakistani and European geographers and travelers, including Makran Sea and Akhzar Sea.
Until the 18th century it was known as Makran Sea and is also visible on historical maps and museums.
The Western side of the gulf connects to the Strait of Hormuz, a strategic route through which a third of the world's liquefied natural gas and 20% of global oil consumption passes from Middle East producers.
In 2018, scientists confirmed the Gulf of Oman contains one of the world's largest marine dead zones, where the ocean contains little or no oxygen and marine wildlife cannot exist. The dead zone encompasses nearly the entire 165,000-square-kilometre (63,700 sq mi) Gulf of Oman, equivalent to the size of Florida, United States of America. The cause is a combination of increased ocean warming and increased runoff of nitrogen and phosphorus from fertilizers.
In 2018, a rail tunnel under the sea was suggested to link the UAE with the western coast of India. The bullet train tunnel would be supported by pontoons and be nearly 2,000 kilometres (1,200 mi) in length.
In the Battlefield video game series, the Gulf of Oman is a map used in Battlefield 2, Battlefield 3, Battlefield Play4Free and Battlefield 4 with the United States Marines Corps (USMC) invading the shore of Oman with the fictional Middle Eastern Coalition (MEC) defending it in Battlefield 2, and with Russian Ground Forces defending it in Play4Free, Battlefield 3 and Battlefield 4.
