Al Ain Oasis is the largest oasis in the city of Al Ain, within the Emirate of Abu Dhabi, the United Arab Emirates.
It is located north of the Al Mutawa'a district and east of the Al Jhali district. The main central district of Al-`Ain is to the north, with the border between Al-`Ain City and the `Omani Town of Al Buraimi to the northwest.
Adjacent to the oasis are Al Ain National Museum to the east and Al Ain Palace Museum to the west. To south is Al Ain Sports Club. To the southwest are Al Ain Etisalat Building and the Oasis Hospital.
The oasis is known for its underground irrigation system "falaj" which brings water from boreholes to water farms and palm trees. The falaj irrigation is an ancient system dating back thousands of years and is used widely in `Oman, UAE, India, Iran, and other countries.
Al`Ain City has seven oases; the smallest is Al Jahili Oasis. The rest are Qattara, Al Mutaredh, Al Jimi, Al Muaiji, and Hili.
