NGC 1559 is a barred spiral galaxy in the constellation Reticulum. It was discovered on 6 November 1826 by Scottish astronomer James Dunlop.{{cite web | url = https://cseligman.com/text/atlas/ngc15a.htm#1559 | title = NGC 1559 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 16 August 2024 }}

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,{{citation

}} NGC 1559 has massive spiral arms and strong star formation. It contains a small bar which is oriented nearly east-west and spans 40{{pprime}}. Its bar and disc are the source of very strong radio emissions.
