The Persian Gulf Residency was a subdivision of the British Empire from 1822 until 1971, whereby the United Kingdom maintained varying degrees of political and economic control over several states in the Persian Gulf, including what is today known as the United Arab Emirates and at various times southern portions of Iran, Bahrain, Kuwait, Oman, and Qatar.

The Persian Gulf, sometimes called the Arabian Gulf, is a mediterranean sea in West Asia. The body of water is an extension of the Indian Ocean located between Iran and the Arabian Peninsula. It is connected to the Gulf of Oman in the east by the Strait of Hormuz. The Shatt al-Arab river delta forms the northwest shoreline.
