Washington County Texas map

The county lies on the west side of the Brazos, about 70 miles northwest of Houston by US-290 and roughly 30 miles south of the Bryan–College Station line. This is post-oak savannah on the Gulf Coastal Plains: open pasture, scattered oak mottes, sandy loam over the older Brazos terraces, and no hills of consequence.

Seven counties surround it. Brazos is north across the river, Grimes northeast, Waller east, Austin south, Fayette southwest, Lee west and Burleson northwest.

The nearest city pages on this site are College Station, 29 miles north in a straight line, and Bryan at 32 miles. Houston is 70 miles southeast, Conroe and The Woodlands about 57 miles east. The 2020 census counted 35,805 residents; the Census Bureau's 2024 estimate is about 37,810.

Washington was one of the original counties of the Republic of Texas, organized in 1837 out of the Mexican municipality of the same name, and it is named for George Washington. Its early boundaries were large enough that Burleson and Lee counties were later cut in part from its territory.

Those are the only two incorporated places, and together they hold under half the county's people. The rest live on farm roads and in unincorporated communities: Chappell Hill and William Penn to the east, Independence to the north, Washington on the river, Gay Hill, Greenvine and Wesley in between.

Burton, 12 miles west of Brenham on US-290, keeps the Burton Farmers Gin, a cotton gin built in the early twentieth century whose original engine still exists in working order — the reason the town holds a cotton gin festival each spring. Independence, north of Brenham on FM 390, was the first site of Baylor University before it moved to Waco in the 1880s, and the columns of the old female-college building still stand on the hill.

Chappell Hill, on FM 1155 just north of US-290, has a brick main street of nineteenth-century storefronts and is the best-known stop on the county's spring bluebonnet routes. FM 390 west of Independence, the old La Bahía road, is the other one.

The site sits on the county's northeastern edge, where the Navasota River joins the Brazos, reached by FM 1155 north from Chappell Hill. In March 1836, while the Alamo was under siege far to the southwest, 59 delegates convened here, adopted the Texas Declaration of Independence, wrote a constitution and formed an interim government, then scattered ahead of the advancing Mexican army. Washington was the seat of the Republic's government again from 1842 until annexation in 1845.

The state historic site preserves the townsite, a reconstruction of Independence Hall, the Star of the Republic Museum and Barrington Living History Farm, the home place of Anson Jones, the Republic's last president. The town itself withered after the railroad went to Brenham instead, which is why the capital of a country is now a park in a pasture.

The Brenham Creamery Company opened in 1907 to make butter from local farmers' cream, started making ice cream a few years later, and renamed itself Blue Bell Creameries in 1930 after the native bluebell flower. The plant on the north side of Brenham is the county's best-known employer and runs a visitor centre; the brand stayed regional for decades and is still not sold nationwide.

Around it, the county runs cattle, hay and horses on the same rolling pasture, with a long-standing cluster of Angus and Brahman breeders. Cotton, once the dominant crop and the reason for the gins at Burton and Brenham, is largely gone. Blinn College, a two-year college founded in Brenham in the 1880s, is the other major institution, and its Brenham campus feeds transfer students to College Station.
