Alvarado Park Lake is a reservoir in Johnson County, Texas 2 miles (3.2 km) southwest of Alvarado, Texas. The county-owned reservoir was built in 1966 by Jack P. McKinney for floodwater retention, municipal water storage, and recreation. It is controlled by the City of Alvarado.

The lake is formed by damming the Turkey Creek, a tributary of Chambers Creek and the Trinity River. It drains 31 square miles (80 km) and is impounded by a 3,500-foot-long (1,100 m) dam 49 feet (15 m) high with a spillway level of 704.1 feet (214.6 m). The water is stained to murky due to sediment.

The nearest major highways are I-35W and US Hwy 67, each approximately 3 miles (4.8 km) from the lake.
