Anderson Mill is a neighborhood of Austin and a former census-designated place (CDP) in Travis and Williamson counties in the U.S. state of Texas.

According to the United States Census Bureau, the CDP has a total area of 1.4 square miles (3.6 km2), all land.

It was not until the late 20th century with the growth of the area as a suburb of Austin that Anderson Mill came back into existence.

The first houses were built in 1975, and construction continued into 1985 with the completion of approximately 3400 homes.

In 1988, at the MUD's request, the Texas Water Commission approved a name change to the Anderson Mill Municipal Utility District.

The area has seven neighborhood parks, two junior olympic swimming pools, eight lighted tennis courts, six extensive playscapes, two basketball courts, three sand volleyball courts, six pavilions of various sizes, an athletic field with both soccer and softball fields and nearly six miles of hike and bike trails that meander through the neighborhood following Lake Creek and its tributaries.

In 2008, the growing City of Austin annexed the MUD and took over the water and wastewater services.

An agreement with the City of Austin and the MUD allowed the residents of the district to voted to create the Anderson Mill Limited District which would retain possession of all the park and recreation facilities.

18.7% of all households were made up of individuals, and 3.7% had someone living alone who was 65 years of age or older.
