This is a discography of official releases by the pop duo PJ & Duncan, who were later rebranded as Ant & Dec.

PJ & Duncan began their musical career in 1993 with the release of the single "Tonight I'm Free". This was followed in 1994 by their successful debut album Psyche, which included the single "Let's Get Ready to Rhumble". Their second album Top Katz (1995) was less commercially successful than Psyche although all its singles reached the UK Top 20. PJ & Duncan were rebranded as Ant & Dec in 1996, resulting in 1997's The Cult of Ant & Dec, their final album, which reached 15 in the UK charts. Their label, Telstar Records, decided not to renew their recording contract in 1997, and their career in music ended there. They reunited for live performances in 2000 and 2013 and for a single, "We're on the Ball", in 2002.
