NameExoWorlds (also known as IAU NameExoWorlds) is the name of various projects managed by the International Astronomical Union (I.A.U.) to encourage names to be submitted for astronomical objects, which would later be considered for official adoption by the organization.

The first such project (NameExoWorlds I), in 2015, mostly regarded the naming of stars.[1] 573,242 votes were submitted by members by the time the contest closed on October 31, 2015, and the names of 31 exoplanets and 14 stars were selected from these.[2] Many of the names chosen were based on world history, mythology and literature.[3] In June 2019, another such project (NameExoWorlds II), in celebration of the organization's hundredth anniversary, in a project officially called IAU100 NameExoWorlds,[4][5] welcomed countries of the world, to submit names for exoplanets and their host stars.[6][7] A star with an exoplanet was assigned to each country, and members of the public submitted names for them.
