Saguache County (suh-WATCH /səˈwɑːtʃ/) is a county located in the U.S. state of Colorado. The county seat is Saguache.

Saguache County was formed December 29, 1866 in the Territory of Colorado, when it was extracted from the northern half of Costilla County. A partition from Lake County on February 9, 1872, added the northwest section of the present-day county.

According to the U.S. Census Bureau, the county has a total area of 3,170 square miles (8,200 km²), of which 3,169 square miles (8,210 km²) is land and 1.7 square miles (4.4 km²) (0.05%) is water. It is the 7th largest of Colorado's 64 counties.
