NGC 6104 is a barred spiral galaxy located in the constellation Corona Borealis. It is designated as S(R)Pec in the galaxy morphological classification scheme, though it is clearly a barred spiral (deserving of the SB(R)Pec designation), and was discovered by William Herschel on 16 May 1787. The galaxy is approximately 388 million light-years away.^[1]^[2]^[3]

Two supernovae have been observed in NGC 6104: SN 2002de (type Ia, mag. 16),^[4] and SN 2019svd (type Ib/c, mag. 19.3).^[5]
