WR 102ea is a Wolf–Rayet star in the Sagittarius constellation. It is the second brightest star in the Quintuplet cluster after WR 102hb. With a luminosity of 2500000 times solar it is also one of the most luminous stars known. Despite the high luminosity it can only be observed at infra-red wavelengths due to the dimming effect of intervening dust on visual light.
