Austin Executive Airpark (FAA LID: 3R3), formerly known as Tim's Airpark (in the 1960s and 1970s), was a public-use airport located in Austin, Texas, United States. It was located near the intersection of Parmer Lane and Interstate 35.

The property was purchased by nearby Dell Computers with the intentions of using it to expand its warehouse facilities. The airport was permanently closed on May 1, 1999.

In 2011, another existing airport, Bird's Nest Airport (FAA LID: 6R4), located in nearby Manor, Texas, was expanded and renamed Austin Executive Airport.
