NGC 1448 is an unbarred spiral galaxy seen nearly edge-on in the constellation Horologium. It is at a distance of 55 million light years from Earth. It was discovered by British astronomer John Herschel on 24 October 1835. Herschel observed the galaxy again on 14 December 1835, resulting in it being listed twice in the New General Catalogue, as NGC 1448 and as NGC 1457.

From the spectral analysis of SN 2001el, over a dozen diffuse interstellar bands were discovered in NGC 1448 – one of the few cases that these bands were observed outside of the Milky Way. However, the bands were significantly weaker at SN 2003hn.

In January 2017 it was announced that evidence for a supermassive black hole in NGC 1448 had been found in the center of the galaxy.

The galaxy belongs to the NGC 1433 group, part of the Doradus cloud of galaxies.

Supernovae

Six supernovae have been observed in NGC 1448:

• SN 1983S (type II, mag. 14.5) was discovered by Robert Evans on 6 October 1983.
• SN 2001el (type Ia, mag. 14.5) was discovered by Berto Monard (bio-fr) on 17 September 2001. It reached magnitude 12.3, making it the brightest supernova of 2001.
• SN 2003hn (type II, mag. 14.1) was discovered by Robert Evans on 25 August 2003.
• SN 2014df (type Ib, mag. 14) was discovered by Berto Monard on 3 June 2014.
• SN 2020zbv (type IIP, mag. 18.83) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 10 November 2020.
• SN 2021pit (type Ia, mag. 13.5) was discovered by ASAS-SN on 10 June 2021.
