UGC 8335 (Arp 238) is a pair of strongly interacting spiral galaxies. They have been distorted by extreme tidal forces, creating prominent tidal tails and a bridge of gas and stars between the galaxies.{{Cite web|title = HubbleSite - NewsCenter - Cosmic Collisions Galore!|date=2008-04-24|url = http://hubblesite.org/newscenter/archive/releases/2008/16/image/ah/|website = hubblesite.org|accessdate = 2015-12-10}}{{Cite web|title = Astronomy Picture of the Day: 4/19/13 - UGC 8335|url = http://futurism.com/astronomy-picture-of-the-day-41913-ugc-8335/|website = Futurism|publisher = |accessdate = 2015-12-10|language = en-US}}

UGC 8335 is about 400 million light-years from Earth, in the constellation Ursa Major. It is the 238th object in Halton Arp's Atlas of Peculiar Galaxies.
