Sagerton is an unincorporated community in Haskell County, Texas, United States.

According to the Handbook of Texas, the community was established in 1905 and named for W. M. Sager, the townsite donor.

It was a shipping point for locally grown agricultural products such as cotton, cattle, and poultry on the newly constructed Kansas City, Mexico and Orient Railway.

[3] Fires in 1917 and 1926 caused extensive property damage, and the town's bank, organized in 1908, failed in 1931.
