格兰德河（英语：Rio Grande）是位于北美南部的河流，在墨西哥被称为布拉沃河（西班牙语：Río Bravo），更正式的称呼为北七拉沃河（西班牙语：Río Bravo del Norte）。

全长3034公里，是美国第五长的河流，并作为美墨边境长约2000公里，流域面积57万平方公里。

起源于科罗拉多州的圣胡安山脉，先往西再从北至南把新墨西哥州分为两份，并在艾尔帕索开始成为美墨的界河，一直到注入墨西哥湾为止。

大部分气候比较干燥（夏季多暴雨），植被稀疏。

The Rio Grande (/ˈriːoʊ ˈɡrænd/ or /ˈriːoʊ ˈɡrɑːndeɪ/; Spanish:Río Bravo del Norte, pronounced: [ˈri.o ˈβɾaβo ðel ˈnorte] or simply Río Bravo) is one of the principal rivers in the southwest United States and northern Mexico (the other being the Colorado River). The Rio Grande rises from south-central Colorado in the United States and flows to the Gulf of Mexico. Along the way, it forms part of the Mexico–United States border. According to the International Boundary and Water Commission, its total length was 1,896 miles (3,051 km) in the late 1980s, though course shifts occasionally result in length changes. Depending on how it is measured, the Rio Grande is the fourth- or fifth-longest river system in North America.
