288 Glauke (/ˈɡlɔːk/ GLAW-kee) is an asteroid from the asteroid belt discovered by Robert Luther in 1890. It was the last of his asteroid discoveries. It is named after Glauke, a daughter of Creon a king of Corinth in Greek mythology.

Glauke has an exceptionally slow rotation period of about 1200 hours (50 days).[2] This makes it one of the slowest-rotating asteroids in the Solar System. The rotation is believed to be "tumbling", similar to the near-Earth asteroid 4179 Toutatis.
