Bentsen-Rio Grande Valley State Park is located at 2800 S. Bentsen Palm Drive (FM 2062) south of the city of Mission in Hidalgo County in the U.S. state of Texas. It serves as the headquarters for the World Birding Center.
The park had its beginnings on January 28, 1944, when the parents of Senator Lloyd Bentsen, Lloyd M. Bentsen Sr. and his wife Edna Ruth Bentsen, along with Elmer and Marie Bentsen, donated 586 acres (237 ha) of land to the State Parks Board for a nature habitat.  The park currently encompasses 764 acres (309 ha) 
The park has become a prime area for bird watching and butterfly watching. When the Bentsen-Rio Grande Valley State Park became the headquarters  of the World Birding Center's network of nine sites in 2004, vehicular traffic was banned and RV camping was no longer allowed in the park. The other sites, all located in south Texas, include Edinburg Scenic Wetlands;  Harlingen Arroyo Colorado, Resaca de la Palma State Park, Roma Bluffs, Quinta Mazatlan, Old Hidalgo Pumphouse Nature Park, Estero Llano Grande State Park, South Padre Island Birding and Nature Center. More than 325 species of birds, and more than 250 species of butterflies have been noted in the Bentsen park.  The park is popular to butterfly watchers.  The North American Butterfly Association  operates the National Butterfly Center adjacent to the park.
