Feature type	Impact crater
Location	Kuiper quadrangle, Mercury
Coordinates	17°30′N 2°54′W / 17.5°N 2.9°W / 17.5; -2.9
Diameter	126 km (78 mi)
Eponym	Ernest Hemingway

Hemingway is a crater on Mercury. It has a patch of very dark material located near its center. The dark color is likely due to rocks that have a different mineralogical composition from that of the surrounding surface.

The crater's name was adopted by the International Astronomical Union (IAU) in 2009. It is named for the American author Ernest Hemingway.

The small crater Makeba is southeast of Hemingway.

Dark interior crater

The dark impact crater near the center of Hemingway is truly black, and due to its superposition over the other structures in the crater, it is a young feature. The dark material is probably abundant in the subsurface of the crater and is being exposed by mass wasting processes and the formation of hollows.
