Gerard Peter Kuiper, born Gerrit Pieter Kuiper (1905 - 1973) was an American astronomer, born in the Netherlands.

Kuiper has discovered a number of satellites (moons) of the planets in the solar system, and suggested the existence of a belt outside Neptune's orbit, now named the Kuiper belt.

In the 1960s, Kuiper also helped identifying landing sites on the moon for the Apollo program.
