368 Haidea is a large asteroid residing in the asteroid belt.{{Cite web |url=https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=368;cad=1 |title=368 Haidea (1893 AB) |work=JPL Small-Body Database |publisher=NASA/Jet Propulsion Laboratory |access-date=11 May 2016}} It was discovered by Auguste Charlois on 19 May 1893 in Nice.

Its name meaning is not known; it may be taken from the opera Haydée or one of several fictional characters named Haidée. The Tagish Lake meteorite is believed to derive from 368 Haidea, due to its reflectance spectrum.Asteroids: Overview, Abstracts, and Bibliography. (2002:78). United States: Nova Science Publishers.
