Cajal is a small lunar impact crater on the northern part of the Mare Tranquilitatis. It is a circular (9 km diameter), cup-shaped formation that lies southeast of the lava-inundated crater Jansen. Orbital imagery shows no significant degradation of the crater from subsequent impacts. To the northwest is a system of wrinkle ridges designated the Dorsa Barlow.[3]

Formerly identified as satellite crater Jansen F,[4] this feature was named after the Spanish doctor and Nobel laureate Santiago Ramón y Cajal (1852-1934). Its designation was officially adopted by the International Astronomical Union in 1973.[1]
