Lavon Lake is a fresh water impoundment located in Collin County, Texas on the East Fork of the Trinity River near Wylie off of State Highway 78. It is commonly called Lake Lavon for commercial and recreational purposes but Lavon Lake is its official name according to the U.S. Army Corps of Engineers. It was originally called Lavon Reservoir.

The lake serves as water source for various north Texas cities.

Started in 1948 and completed in 1953 the Lavon Dam was created to impound the upstream East Fork of the Trinity River, many of its tributaries and the areas immediately surrounding them. The reservoir was primarily designed for preventing seasonal flooding of rich bottomland in southeastern Collin County and water storage. Its construction also stimulated land development along the shores of the lake and recreational use of the water and adjacent land areas. In 1962, Congressional approval was given to modify the project to increase storage for water supply because of the growing water supply need of the area.

Lavon Lakes's dominant fish species are the largemouth bass, white bass, blue catfish, and crappie.
