Grit is an unincorporated farming and ranching community established ca.1889 in Mason County, in the U.S. state of Texas.

The initial settlers considered naming the community after Congressional Medal of Honor recipient Frederick Funston, but a Funston, Texas already existed in Jones County and there was concern of postal delivery confusion.

The town is located on Texas State Highway 29, 6 miles (9.7 km) northwest of Mason, near Honey Creek.

The prevailing theory of the town's name is that it reflects the quality of the area soil.

[6][7] Grit received a post office in 1901, which remained active until 1980.
