Calling Card is the sixth studio album and eighth album overall by Irish singer and guitarist Rory Gallagher. Released in 1976, it marked the second of four albums he released on Chrysalis Records during the 1970s. The album was co-produced by Gallagher and Roger Glover, the bassist for Deep Purple and Rainbow. This collaboration was notable as it was Gallagher's first experience working with a high profile producer and remains his only successful partnership of such collaboration.
