WASP-67 is a K-type main-sequence star about 620 light-years away. The star's age is poorly constrained. WASP-67 is slightly depleted in heavy elements, having 85% of the solar abundance of iron.
A multiplicity survey in 2016 has found one candidate stellar companion to WASP-67 at a projected separation of 4.422″±0.018″. Nonetheless, follow-up observations in 2017 failed to find any bound stellar companions.
