Dorado is a constellation in the Southern Sky. It was named in the late 16th century and is now one of the 88 modern constellations. Its name refers to the mahi-mahi, which is known as dorado ("golden") in Spanish, although it has also been depicted as a swordfish. Dorado contains most of the Large Magellanic Cloud, the remainder being in the constellation Mensa. The South Ecliptic pole also lies within this constellation.

NGC 1783 is a globular cluster within the Dorado constellation and part of the Large Magellanic Cloud, a satellite dwarf galaxy of the Milky Way. At an aperture of 50 arcseconds, its apparent V-band magnitude is 10.39, making it one of the brightest globular clusters in the LMC as viewed from Earth. It was discovered in 1835 by John Herschel. The compiler of the New General Catalogue, John Louis Emil Dreyer, described this cluster as "considerably bright, large, round, very gradually pretty much brighter middle, mottled but not resolved."

NGC 1858 is a bright, large, irregular open cluster and emission nebula. It is found in the Dorado constellation. It is located in the Large Magellanic Cloud. It was first discovered by James Dunlop on August 3, 1826, and was first recorded as Dunlop 120. John Herschel recorded it on November 2, 1834. However, at the time, he did not associate it with Dunlop 120. Astronomers have now realised that Dunlop 120 and NGC 1858 are the same object.
