Carnegie is a town in Caddo County, Oklahoma, United States. The population was 1,430 as of the 2020 United States census.

Carnegie was named after the famous Scottish American industrialist and philanthropist, Andrew Carnegie. The initial name of the town was Latham. The town was originally platted as North and South Latham, with North Latham being north of the Washita River, and South Latham being south of it. North Latham was intended to be the commercial hub, with the Chicago, Rock Island and Pacific Railway expected to go along the north side of the river. However, the tracks ended up running along the south bank of the Washita, so South Latham became the commercial hub and North Latham withered and/or was never developed.

Leaders of the town decided shortly after incorporation in 1903 to rename the town Carnegie in the hopes the industrialist would build a library there. Although the town acquired a library, Andrew Carnegie did not provide it. Of note, there is unofficially a "Carnegie Hall", known more properly as the Carnegie Memorial Auditorium, where community events are held. While currently on hiatus, for several years there was an annual "Stars of Carnegie Hall" talent show showcasing individuals across the region and state in a local talent show, in which both local and regional talents were represented.

Carnegie High School has won three state titles in boys basketball (1988, 1992, 1996), as well as three titles in girls cross country (2002, 2003, 2004). Carnegie High also has three won state titles in boys cross country (1999, 2000, 2020). The Kiowa Tribe of Oklahoma headquarters are located in Carnegie.

According to the United States Census Bureau, the town has a total area of 1.37 square miles (3.55 km), all land.

The town is on the south bank of the Washita River, 27 miles (43 km) west of Anadarko, at the intersection of state highways 9 and 58.
