Lacerta (genitive Lacertae, abbreviation Lac), the Lizard, is one of the minor constellations. It is located between Cygnus, Cassiopeia and Andromeda. The active galaxy BL Lacertae is one of the notable objects within this constellation. BL Lac was discovered quite early, and first believed to be a star, and therefore named like variable stars.

In the Science Fiction novel Diaspora by Greg Egan, the constellation Lacerta was the origin of a massive shock wave, caused by the collision of two Neutron Stars, which caused the extinction of most life on Earth.
