Moody has won six Premiership titles and two European Cups at Leicester
Bath have signed England flanker and World Cup winner Lewis Moody from Leicester on a three-year deal.
The 31-year-old will arrive at the Recreation Ground in the summer having made his professional debut with the Tigers while a schoolboy in 1996.
Moody made his England debut against Canada in 2001 and has won 59 caps.
He said: "I have always known that if I was ever going to leave Leicester, the only club I would consider in the UK would be Bath."
He continued: "They play an exciting brand of rugby and having spent time with both [coach] Steve Meehan and [chief executive] Nick Blofeld, I am sure that there are exciting years ahead.
Bath's values perfectly suit my own - it is a great city and club, with a real family feel and a close knit and impressive squad
"I am really looking forward to an exciting new challenge at this stage of my career.
"Bath's values perfectly suit my own - it is a great city and club, with a real family feel and a close knit and impressive squad."
Bath coach Steve Meehan said: "We're very pleased he's coming to the club but at the same time it shows he wants a change in playing style and direction.
"The first time I spoke to him was Wednesday of last week and it all moved very quickly which is a terrific reflection on the club and a terrific reflection on him.
"You only have to look at the guy to see what an athlete he is so to improve the depth of our back row and the dynamism that he will bring can only be a good thing."
Moody was a key part of England's 2003 World Cup winning squad, coming off the bench in the final.
Two years later he went on to become a British and Irish Lion, winning three caps on the tour of New Zealand.
He made his senior debut for Leicester while still at school in August 1996 and became the youngest Tiger to figure in a league match.
Since then Moody has gone on play more than 200 times for the Welford Road club, scoring 34 tries.
He has picked up six Premiership titles and two European Cups in his time with Leicester.
Moody becomes Bath's third signing for next season, following the capture of Newcastle winger Tom Biggs and Glasgow scrum-half Mark McMillan.
