Azle (/ˈeɪzəl/ AY-zəl) is a city west of Fort Worth in Parker and Tarrant Counties in the U.S. state of Texas.

The first recorded settlement at the site occurred in 1846, when James Azle Steward, a young doctor, moved into a log cabin built by a Dutchman named Rumsfeldt.

[5] The first post office opened in 1881, and the town took the name of O'Bar, in honor of the man who obtained the postal service.

Dairy farming became important in the early decades of the 20th century, when local milk products were sold to creameries in Fort Worth.

After the 1930s, agriculture gradually declined; fields were converted from wheat and corn production to housing developments.

The Azle High School Math/Science and Journalism teams combined won the 2005 UIL State Academic Meet championship with a total of 110 points.
