SMTV Live (an abbreviation of Saturday Morning Television Live also written 'SM:TV Live' and in early promotional material 'SMTV://live') was a British Saturday morning children's television programme, first broadcast on ITV on 29 August 1998 and last broadcast on 27 December 2003. On the surface it did not seem to stray away from the format of other Saturday morning programmes, featuring an audience of children, competitions and cartoons, though it constantly won in ratings battles with the BBC version, Live & Kicking, and gave ITV their most watched children's programme since Tiswas.

This show and "CD:UK" (1998) were effectively the same programme, sharing most of the same production team and presenters (until early 2002), the same studio (until September 2003) and with guests from the show appearing on CD:UK.

Originally, SM:TV and CD:UK were made by Ant and Dec's own production company, which was a division of Zenith. In 1999, Blaze Television was set up by Zenith as a music and entertainment division of the company, and SM:TV and CD:UK became produced by Blaze.

After SM:TV was cancelled, both SM:TV & CD:UK moved from a shared studio The London studios to different studios (CD:UK had the big studio, SM:TV rented out a small area - much smaller than what they had before) at The Riverside Studios in Hammersmith in September 2003. Shortly after this, SM:TV Live became SM:TV Gold for the rest of its run - consisting of old clips and live links.

Is one of only four British Saturday morning shows to run all year round, and was the first and longest running (as of October 2004) - from August 1998 until the show ended in December 2003. The only other shows to do this are BBC1's "Live & Kicking" (1993) between September 2000 until September 2001 and "Saturday Show, The" (2001) Between September 2001 and September 2003 (the show is currently Summer only) and SM:TVs replacement "Ministry of Mayhem" (2004) from January 2004.
