1421 Esperanto (provisional designation: 1936 FQ) is an asteroid from the asteroid belt discovered on March 18, 1936 by the Finnish astronomer Yrjö Väisälä at Iso-Heikkilä Observatory in Turku, Finland. It is about 43 km in diameter.

Väisälä named the asteroid after the constructed language Esperanto. He also named another asteroid, 1462 Zamenhof, after Esperanto's creator, L. L. Zamenhof. The two asteroids are considered to be the most remote Zamenhof-Esperanto objects.
