Carthay Circle is a neighborhood in west-central Los Angeles, California. It is considered part of the Fairfax District. Its boundaries include areas such as Picfair (whose name is a tribute to Mary Pickford's and Douglas Fairbanks' estate, Pickfair), South Carthay, Carthay Square, and Little Ethiopia, a community of relatively recent Ethiopian and Indian immigrants.

It is bordered by Country Club Park on the east, Crenshaw on the south, Beverlywood on the west, and the Miracle Mile on the north. Its principal thoroughfares include La Cienega, San Vicente, Pico, and Venice Boulevards and La Brea and Fairfax Avenues. The Santa Monica Freeway runs along its southern edge.

The areas comprising Carthay Circle were mostly developed in the 1930s, capitalizing on the success of the Miracle Mile; most houses are built in the Art Deco or Spanish Colonial styles popular at the time. Initially segregated and all-white, Carthay Circle has since become fairly diverse, with many middle-class black and Latino families living within the district. Much of its white population is Jewish, with several yeshivas and synagogues found in the area.

The neighborhood takes its name from a now-demolished movie theatre which stood on the corner of San Vicente and Crescent Heights boulevards.
