1965–66 Intertoto Cup

The 1965–66 Intertoto Cup was won by 1. FC Lokomotive Leipzig, who had lost the previous season's final (under their previous name of SC Leipzig). They defeated IFK Norrköping. After experimenting with twelve groups totalling 48 clubs for two years (although latterly only 44 clubs were recruited to fill eleven groups), the competition returned to its original format with 32 clubs divided into eight groups. As a result, the clubs went straight to the Quarter-finals after the Group Stage, while in previous seasons a First Round had also been required.
