The Seagull Nebula (IC 2177) is a large region of nebulosity located approximately 3,650 light-years away in the constellation Monoceros (the Unicorn), on the border with Canis Major. The nebula includes an Hii region, open star clusters, dark dust clouds, and reflection nebulae.

The Seagull Nebula has an apparent size about seven times that of the full Moon. It was named the Seagull because its complex of dust and gas forms a shape reminiscent of that of a seagull in flight.

The nebula is composed of interstellar dust clouds and hydrogen, helium, and other gases that are ionized by the energetic young stars formed within the nebula. The radiation of the new stars causes the surrounding hydrogen gas to glow with a reddish colour.

This Hii complex on the border of Monoceros and Canis Major covers about 3 degrees of sky. The nebula lies in one of the farthest arms of our Milky Way galaxy and is about 100 light years across. The head of the Seagull is Vdb 93. Also contained within the nebula are the open clusters NGC 2343, NGC 2335, Collinder 465, and Collinder 466.
