The Guadalupe River (/ˌɡwɑːdəˈlup/; Spanish pronunciation: [gwaðaˈlupe]) runs from Kerr County, Texas, to San Antonio Bay on the Gulf Coast. It is a popular destination for rafting, fly fishing, and canoeing. Larger cities along it include Kerrville, New Braunfels, Seguin, Gonzales, Cuero, and Victoria. It has several dams along its length, the most notable of which, Canyon Dam, forms Canyon Lake northwest of New Braunfels.

The river, and the larger area around it known as Texas Hill Country, is prone to flash flooding. Its nickname is Flash Flood Alley.
