WASP-43b is a transiting planet orbiting the young, active, low-mass star WASP-43 in the constellation Sextans. The planet is a hot Jupiter with a mass twice that of Jupiter, but with a radius approximately equal. WASP-43b was flagged as a candidate by the SuperWASP program, before they conducted follow-ups using instruments at the La Silla Observatory in Chile, which confirmed its existence and provided orbital and physical characteristics. The discovery of the planet was published on April 14, 2011.

At the time of its discovery, WASP-43b had an orbital period of about 0.8 days (19.2 hours), the second shortest orbit ever detected, second only to WASP-19b. In addition, at the time of discovery, WASP-43b was the closest known hot Jupiter orbiting, a phenomenon that can most likely be explained by the low mass of its host star.
