It is said the disgraced presenter made the decision himself but "with the agreement of ITV".
Ross was suspended from his BBC One Friday chat show and his Saturday BBC Radio 2 show by the corporation yesterday for 12 weeks, but no mention was made of his agreements with other channels.
However, a spokesman for Ross said this afternoon: "It's a show he very much enjoys being part of but would not want his participation in this year's event to take away from the awards themselves or the many talented winners of the awards."
The awards, which will be filmed on December 6, will take place during Ross's 12-week BBC ban.
Peter Fincham, director of television at ITV, said: "We respect Jonathan's decision to stand down from the 2008 British Comedy Awards, which has been made with the full support of ITV and the show's producers."
