Alpha Cygni, Deneb, is a bright (1.25) bluish-white supergiant is 3000 light years away.

The star represents the tail of the swan, and is the obvious starting point to the many interesting features of this constellation, as well as a convenient pointer to a number of other stars in the region.

Deneb forms a large triangle (sometimes called the Summer Triangle) with Altair (in Aquila) and Vega, in Lyra: The Summer Triangle.

Deneb has a few Flamsteed numbered stars as neighbours: binoculars.
