Longhorn Dam is a dam located at 30.2504, -97.7135 (WGS 84 datum) on the Colorado River within the city limits of Austin, Texas, USA. Longhorn Dam was built by the city of Austin and finished in 1960 as the last in a chain of Colorado River dams in central Texas started during the Great Depression. The dam derives its name because it was the ford across the Colorado for longhorn cattle drives as a part of the Chisholm Trail in the late 1800s.

The dam stands convert|36|ft|m|0 high and runs convert|506|ft|m|0 across. The "reservoir impoundment length," is convert|5.75|mi|km|1, creating Lady Bird Lake, a freshwater lake with a surface area of convert|525|acre|km2|1 and a convert|12.5|mi|km|1 shoreline. Lady Bird Lake both beautifies the city and ensures a constant water level to form a cooling lake for Austin's Holly Street Power Plant.

On July 10, 2007 two teenage girls canoeing on Lady Bird Lake were sucked through the dam. The lake was closed for recreation due to record amounts of rain in the months of June and July, however the girls were unaware of the ban. Neither of the girls were hurt.
