NGC 5308 is an edge-on lenticular galaxy in the constellation of Ursa Major. It was discovered on 19 March 1790 by William Herschel.{{cite web|url=http://cseligman.com/text/atlas/ngc53.htm#5308|title=New General Catalogue objects: NGC 5300 – 5349|author=Seligman, Courtney|website=cseligman.com|accessdate=21 February 2017}} It was described by John Louis Emil Dreyer as "bright, pretty large" when he compiled the New General Catalogue.{{cite web|url=http://spider.seds.org/ngc/ngc.cgi?NGC5308|title=NGC 5308 – SEDS|website=seds.org|accessdate=21 February 2017}} A small, irregular galaxy near NGC 5308 has been given the designation LEDA 2802348.{{cite simbad|title=LEDA 2802348|access-date=21 February 2017}}

NGC 5308 was imaged by the Hubble Space Telescope in 2016. The galaxy appears to be a flat, smooth disk, typical of most lenticular galaxies. Many large globular clusters orbit the galaxy; these are visible as tiny dots surrounding the galaxy, and are mostly made of old, aging stars similar to the galaxy itself.{{cite web|url=https://www.spacetelescope.org/images/potw1620a/|title=Busy bees | ESA/Hubble|date=2016|website=spacetelescope.org|accessdate=21 February 2017}}
