NGC 1559 is a barred spiral galaxy in the constellation Reticulum. It was discovered on 6 November 1826 by Scottish astronomer James Dunlop.

NGC 1559 is a Seyfert galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable. Although it was originally thought to be a member of the Dorado Group, subsequent observations have shown that it is in fact not a member of any galaxy group or cluster and does not have any nearby companions. NGC 1559 has massive spiral arms and strong star formation. It contains a small bar which is oriented nearly east-west and spans 40″. Its bar and disc are the source of very strong radio emissions.

Four supernovae have been observed in NGC 1559:

Australian amateur astronomer Robert Evans discovered the first three: SN 1984J (type II, mag. 13.5), SN 1986L (type II, mag. 13.5), and SN 2005df (Type Ia, mag 12.3).
SN 2009ib (type IIP, mag. 14.7) was discovered by the CHASE project (CHilean Automatic Supernova sEarch) on 6 August 2009.
