780 Armenia is a minor planet in the asteroid belt orbiting the Sun. It is named after the Kingdom of Armenia, now Armenia.

This object is the namesake of the Armenia family, a very small family of 13–76 asteroids that share similar spectral properties and orbital elements; hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.[2]
