Phocylides is a lunar impact crater located near the southwest rim of the Moon.

Eastward is the merged formation Schiller, and in the southwest lies Pingré.

The outer wall of Phocylides is worn and eroded, especially along the western edge.

The floor of Phocylides is flooded and relatively smooth, with a few small craterlets and no central peak.

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