Secchi is a small lunar crater formation on the northwest edge of Mare Fecunditatis. To the northeast is the Taruntius crater. The western rim is joined with a section of the minor Montes Secchi range. The rim of this crater has been opened in the north and south ends, leaving two curved ridges facing each other across the crater floor. To the south is a pair of rilles designated the Rimae Secchi. These lie near the edge of the mare, and have a combined length of about 40 kilometers.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Secchi crater.
