Little has spent the last three seasons in Italy with Petrarca Padova
Bath have signed Fijian fly-half Nicky Little on a one-year contract.
Little, 32, has previously played in the English Premiership with Sale and Saracens and is his country's highest points scorer from a record 63 caps.
He will compete for the first-team shirt with Ryan Davis while South African Butch James is expected to be sidelined with injury until 2010.
"He's very strong defensively, has plenty of experience and a reliable boot," said head coach Steve Meehan.
"And while he is a relaxed character off the field, he is very competitive on it."
Little spent two seasons at the Sharks after joining them in 1999 before one-year spells with Pontypridd and Dax and three seasons with Saracens from 2003.
Most recently he has been plying his trade with Petrarca Padova in Italy.
Internationally, Little starred at the 2007 World Cup but missed Fiji''s quarter-final against South Africa with a knee injury he suffered in the famous pool win over Wales.
Bath have also boosted their back-row options with Exeter Chiefs and England Sevens player Chris Cracknell arriving on a four-month contract.
"Chris impressed Ben Ryan (England Sevens head coach) so much that he recommended him to me months ago," added Meehan.
"He is fit and working hard and is keen to impress. With Luke Watson not arriving until November it seemed a good match and I know that over the next four months he is determined to do well and push all the back rowers."
As well as South African Watson, Meehan has also strengthened the back row by recruiting Ben Skirving and Julian Salvi over the summer.
