Sapientia (minor planet designation: 275 Sapientia) is a very large Main belt asteroid that was discovered by Johann Palisa on 15 April 1888 in Vienna. It is classified as a C-type asteroid and is probably composed of carbonaceous material. It is named for the Roman personification of wisdom, Sapientia.[2]

Observations performed at the Palmer Divide Observatory in Colorado Springs, Colorado, during 2007 produced a light curve with an estimated period of 14.766±0.006 hours with a brightness range of 0.11±0.02 in magnitude.[3] A 2014 study found a period of 14.931±0.001 hours with a variation of 0.12±0.01 in magnitude. The light curve was found to be irregular, suggesting the asteroid has an irregular shape.[4] On September 30, 2015, the asteroid was observed occulting the 7th magnitude star HIP 14977 from multiple sites in Europe. The resulting chords showed a nearly circular prolate spheroid profile.[5]
