The Mission River is a river located in Texas, in the United States of America. It is formed by the confluence of Blanco and Medio creeks in central Refugio County (at 28°19' N, 97°19' W) and runs southeast, past Refugio, for 24 miles (39 km) to its mouth on Mission Bay, an inlet of Copano Bay (at 28°10' N, 97°10' W). It traverses gently undulating coastal prairies surfaced by clay and loam and spotted by groves of hardwoods and pines. It is home to myriad waterfowl and native slough grasses.
