Gagarin is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon. To the southwest is the crater Pavlov and to the northeast lies Keeler. Closer to the rim are the craters Levi-Civita to the southwest, and Beijerinck to the north-northeast. Isaev lies entirely within the northwest rim of Gagarin. In contrast with the floor of Gagarin, Isaev has a floor with a somewhat low albedo.
The crater was named in by the IAU in 1970, after Soviet cosmoonaut Yuri Gagarin. Prior to naming, Gagarin was called Basin X.
