"Jag ljuger så bra" ("I lie so well") is the third single from Swedish pop singer Linda Bengtzing, released on her debut studio album Ingenting att förlora during the first quarter of 2006. Bengtzing performed the song in Melodifestivalen 2006, finishing seventh in the finale. The song, composed especially for Melodifestivalen by Lars Diedricson, Martin Hedström, and Ingela “Pling” Forsman, was originally written for another artist, Jessica Andersson, who instead chose "Kalla nätter" ("Cold Nights") to perform at the contest.
