Sabine (/ˈseɪbɪn/ SAY-bin) is a lunar impact crater that forms a nearly matching pair with Ritter to the northwest.

About 85 km to the east-southeast is 'Statio Tranquillitatis' (Tranquility Base), the landing site of the Apollo 11 mission and the first human beings to step on the Moon.

In To A Rocky Moon, lunar geologist Don E. Wilhelms summarized: "They are identical twins in morphology and size (29-30 km).

Most significant, they lack deep floors recognized since the days of Gilbert as diagnostic of impacts."

"[2] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Sabine.
