The Emirate of Ajman is one of the seven Emirates (states) of the United Arab Emirates. It has an area of a mere 260 square kilometres (100 sq mi), which makes it the smallest of the emirates in terms of area. It is named after the city of Ajman, which is its seat of government. It is bordered on the north, east, and south by the Emirate of Sharjah. It has a population of some 240,000.

Located on the coast of the Persian Gulf, Ajman also controls two small inland exclaves: Manama and Masfut, both of which are primarily agricultural. Approximately 95% of the population of the emirate resides in the city of Ajman, which forms part of the Dubai-Sharjah-Ajman metropolitan area. Ajman is ruled by Sheikh Humaid bin Rashid Al Nuaimi of the Al Nuaimi tribe. The Crown Prince of the Emirate is Sheikh Ammar bin Humaid Al Nuaimi.
