WASP-107b is a super-Neptune exoplanet that orbits the K-type star WASP-107. It lies 200 light-years away from Earth in the constellation of Virgo. Its discovery was announced in 2017 by a team led by D. R. Anderson via the WASP-South.

== Planetary orbit== WASP-107b could not have formed in its current orbit. It likely migrated inward from its birth orbit beyond 1 AU due to interaction with the heavier planet WASP-107c. It is in a retrograde orbit, strongly misaligned with the equatorial plane of the parent star. The misalignment angle is equal to 118°. WASP-107c follows a highly eccentric and inclined orbit with a period of 1088 days.
