Marie Henri Andoyer (1 October 1862 – 12 June 1929) was a French astronom and mathematician. He published on celestial mechanics of planets, minor planets, the moon and the moons of Jupiter.
He created an approximation formula, the Andoyer approximation for the calculation of the distance of two points on the Earth (or other ellipsoidal bodies), which takes the flattening of the Earth into account (unlike, for example, the Haversine formula)
