The North American Nebula - NGC 7000

This nebula obviously gets its moniker from its resemblance to the continent of North America. The brightest portion corresponds to Mexico, and the brightest region seen there is often referred to as the "Great Wall".  In many images (including some here) it is shown with its close neighbour, the Pelican Nebula, which is part of the same nebula complex.  It lies approximately 2200 light years distant in the constellation Cygnus.
