Alencar is a crater on Mercury. It has a diameter of 120 kilometers.[1] Its name was adopted by the International Astronomical Union (IAU) in 1979. Alencar is named for the Brazilian novel writer José de Alencar, who lived from 1829 to 1877.[2]

Alencar has a complex central peak. On the west side of the central peak complex is a dark spot of low reflectance material (LRM), closely associated with hollows.[3]

Alencar is located to the north of the larger crater Bach.
