Phocylides is a lunar impact crater located near the southwest rim of the Moon. It overlays the south rim of the crater Nasmyth to the north. To the northwest is the unusual plateau formation of Wargentin. 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 northern edge of the rim is notched and irregular, with a rise of ground joining the south rim of Wargentin. The crater Phocylides F lies across the southern rim. The floor of Phocylides is flooded and relatively smooth, with a few small craterlets and no central peak. T. W. Webb called the interior floor monotonous in hue.
