Goclenius is a lunar impact crater that is located near the west edge of Mare Fecunditatis.

A similar rille lies across the floor of Gutenberg, and it is likely that these features were all formed at the same time, after the original craters were created.

There is a low central rise located to the northwest of the crater's midpoint.

The crater is named for Rudolf Goclenius, Jr. (1572–1621), German physician and professor of physics, medicine and mathematics.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Goclenius.
