WASP-88 is a F-type main-sequence star. Its surface temperature is 6450{{±|61}} K. WASP-88 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.03{{±|0.04}}, and is younger at an age of 3.0{{±|1.3}} billion years.

A multiplicity survey did detect a candidate red dwarf companion to WASP-88 in 2020, with a 1.65% probability of it being an unrelated background star.{{citation|arxiv=2001.08224|year=2020|title=A multiplicity study of transiting exoplanet host stars.
