NGC 7752 and NGC 7753 are a set of galaxies approximately 272 million light-years away in the constellation Pegasus.

NGC 7753 is the primary galaxy. It is a barred spiral galaxy with a small nucleus. NGC 77532 is the satellite galaxy of NGC 7753. It is a barred lenticular galaxy that is apparently attached to one of NGC 7753's spiral arms, it would resemble the Whirlpool Galaxy (M51A) and its satellite NGC 5195 (M51B). On January 2, 2006, a supernova (SN 2006A) was observed in NGC 7753. It was the only supernova observed in the NGC 7752 and NGC 7753 galaxies (so far).
