Crates Bay (Bulgarian: залив Кратес, ‘Zaliv Krates’ \'za-liv 'kra-tes\) is the 8 km wide bay indenting for 6 km the northeast coast of Stresher Peninsula, Graham Coast on the Antarctic Peninsula. It is part of Holtedahl Bay, entered southeast of Starmen Point and northwest of the headland formed by Lens Peak. Conway Island lies in the central part of the bay. Crates Bay was formed as a result of glacier retreat during the last three decades of the 20th century.
