Dorothy Crater is the official name used to describe two features in the solar system; an impact crater on Venus, and a large impact basin on Pluto's moon, Charon.

Dorothy Crater is the largest known impact basin on Pluto's moon Charon. The crater was discovered by the New Horizons space probe in 2015 during its flyby of Pluto and its moons. It was named after Dorothy Gale from the novel The Wonderful Wizard of Oz.[1] The crater is located near Charon's north pole, and overlaps the edge of Mordor Macula.

The names for small craters on Venus (with a diameter less than 20 km) are chosen from common female names.[3] Dorothy is a Greek first name, and the crater was officially designated by the IAU in 1997. The crater is east of Tamfana Corona, and south of Seoritsu Farra.[4]

Like many impact craters on Venus, Dorothy has been flooded and buried by lava flows.[5]
