NGC 1858 is a star formation region located on the northwestern edge of the Bar of the Large Magellanic Cloud and embedded in the H-II region N105A . The age of the newly formed star cluster in the area is estimated to be around 8 to 10 million years. The discovery of a protostar is an indication that NGC 1858 is still an active star formation region.
The area was discovered in 1826 by the astronomer James Dunlop with a 23 cm telescope and described as a star cluster surrounded by a nebula; this observation was later recorded in the New General Catalog .
