LHA 120-N 55 or N55 is an emission nebula located within the Large Magellanic Cloud (LMC). N55 is situated inside a superbubble called LMC 4. It is a glowing clump of gas and dust that gets its light output from the hydrogen atoms shedding electrons within it. It was named in 1956, in a catalogue of H-alpha emission line objects in the LMC.

Multiple dense molecular clumps have been detected, at least fifteen of which contain young stellar objects.
