The bright star 75 Peg is a close binary ellipsoidal variable with a short period (0.5021035-day) and an extreme mass ratio of 0.104 B, V, and R photometric data, along with previously published radial-velocity data, are analyzed; they suggest that the primary of the 75 Peg system may be, or is very close to, filling its critical Roche lobe. 11 refs.
