281 Lucretia is an asteroid belonging to the Flora family in the Main Belt. It was discovered by Austrian astronomer Johann Palisa on 31 October 1888 in Vienna, and is named after the middle name of Caroline Herschel, one of the first female astronomers. Light curves of this asteroid show a synodic rotation period of 4.349±0.001 h with an amplitude of 0.3–0.4 magnitude. The spin axis appears nearly perpendicular to the ecliptic.
