80 Sappho (/ˈsæf/ SAF-oh) is a large main-belt asteroid. It was discovered by Norman Pogson on May 2, 1864, and is named after Sappho, the Greek poet.

13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of 83 kilometres (52 mi).[3]
