NGC 4625 (also IC 3675, Arp 23, IRAS 12395+4132, MCG 7-26-38, UGC 7861 and PGC 42607) is a magnitude +12.4 distorted dwarf galaxy located 27 million light years away in the constellation Canes Venatici. 
Unlike most spiral galaxies, NGC 4625 has a single spiral arm, which gives the galaxy an asymmetric appearance. It has been hypothesized that this galaxy's asymmetric structure may be the result of a gravitational interaction with NGC 4618: these two galaxies are listed as Arp 23 in the Atlas of peculiar galaxies by Halton Arp.

The galaxy was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Windsor Road, Slough, on the 9th April 1787.
The galaxy was rediscovered by Max Wolf in March 1903 and relisted as IC 3675.
