WASP-41 is a G-type main-sequence star. Its surface temperature is 5450{{±|150}} K. WASP-41 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of −0.080{{±|0.090}}, but is much younger at an age of 2.289{{±|0.077}} billion years. The star does exhibit strong starspot activity, with spots covering 3% of the stellar surface.

Multiplicity surveys did not detect any stellar companions as of 2017.{{citation|arxiv=1709.07476|title=High-resolution Imaging of Transiting Extrasolar Planetary systems (HITEP). II.
