The list of rivers of Texas is a list of all named waterways, including rivers and streams, that partially pass through or are entirely located within the U.S. state of Texas. Across the state, there are 3,700 named streams and 15 major rivers, accounting for over 80,000 mi (130,000 km) of waterways. All of the state's waterways drain towards the Mississippi River, the Texas Gulf Coast, or the Rio Grande, with mouths located in seven major estuaries.
This list is arranged by drainage basin, with tributaries indented under each larger stream's name listed in order from mouth to source.
Of these ten rivers, all empty into the Gulf of Mexico. Four of the rivers are tributaries: the Pecos flows into the Rio Grande, the Red into the Mississippi River, and the Sabine and Neches flow into Sabine Lake, which is connected to the Gulf of Mexico by the Sabine Pass. The Canadian is a tributary of a tributary. It flows into the Arkansas River, which is itself a tributary of the Mississippi.
The Trinity River is the longest river with its entire drainage basin in Texas. The Colorado is the longest river with both its source based on river name and its mouth in the state. The actual longest source of the Colorado is in New Mexico.
