Dawson County Texas map
32.74° N · 101.95° W · County seat: Lamesa · 902 sq mi
Dawson County is a cotton county with a statistical distinction: the Lamesa micropolitan area, which is exactly this one county, is the smallest micropolitan statistical area in the United States by population. Six numbered highways converge on Lamesa, and almost everything they carry has to do with cotton, oilfield supply or the drive between Lubbock and Midland.
Lamesa sits at the crossing of US-87 and US-180 near the center of the county, roughly halfway between Lubbock and Midland.
Where Dawson County is
Dawson lies on the southern edge of the Llano Estacado, where the South Plains farm country runs into the oil counties of the Permian Basin. Six counties border it: Lynn north, Borden east, Howard southeast, Martin south, Gaines west and Terry northwest.
Lamesa is about 58 miles south of Lubbock and 52 miles north of Midland on US-87, which makes Dawson County the middle third of one of the busiest two-lane corridors in West Texas. Big Spring is 44 miles southeast on US-180 and Odessa 67 miles southwest.

Roads through Lamesa
- US-87 – north–south, Lubbock to Lamesa to Big Spring and San Angelo; the county's main street and the reason Lamesa exists as a trade town.
- US-180 – east–west, from Seminole in Gaines County through Lamesa toward Snyder.
- SH-349 – south from Lamesa to Midland, the shortest paved line between the two.
- SH-137 – southeast toward Stanton and Ackerly.
- SH-115 – west into Gaines County.
- SH-83 – the shorter state route serving the county's northern farm sections.
Cotton, the smallest micro area, and a 22-person city
Dawson County is one of the top cotton-producing counties in Texas most years. The crop is grown both dryland and under center pivots drawing on the southern rim of the Ogallala aquifer, which is shallower and less generous here than it is 60 miles north; that limit is why so much of the county's acreage is dryland and why yields swing hard with the summer rain. Gins, module trucks and a compress operation in Lamesa are the visible end of it.
Because the Census Bureau defines a micropolitan area around any urban cluster of 10,000 to 50,000, Lamesa qualifies with only its own county attached — and with 12,456 residents it is the least populous such area in the country. The county's 2024 estimate of 11,758 continues a long slide from its mid-century peak, when cotton took far more hands than it does now.
The oddest place on the county map is Los Ybanez, an incorporated city of 22 people near Lamesa. It was created in the 1980s on a former military housing tract, and what made incorporation worth doing was liquor: an incorporated city could hold its own local-option election and license package stores while the surrounding county stayed dry. The stores drew customers from a wide circle of dry counties, and the city has stayed on the map ever since.
The county's name comes from Nicholas Mosby Dawson, killed in 1842 in the fight near Salado Creek that Texans call the Dawson Massacre — a name attached in 1876 to country he never saw, when the legislature was cutting the huge Bexar District into counties faster than anyone was settling them. Dawson County did not organize a government until 1905.
