Burnley will sign Bournemouth midfield pair Wade Elliott and Garreth O'Connor on free transfers on 1 July.
The pair, both 26, were out of contract and although they were offered improved deals at Dean Court, agreed personal terms over the weekend.
Clarets boss Steve Cotterill said: "I am delighted to agree three-year contracts with both Wade and Garreth.
"They are two lads I know very well - I hope they both play as well as they did the last time they visited Turf Moor."
The pair impressed Cotterill - himself a former Bournemouth player - when the south coast club faced Burnley in the FA Cup fourth round in January.
Cotterill continued: "People will remember Wade from his performance against us in the Cup, when he gave Mo Camara probably the toughest game he had all season.
"They have come to us within the right wage structure, and the fact they were both available on free transfers was a big bonus.
"Both lads have been schooled well by (Cherries boss) Sean O'Driscoll, and we will be looking to hopefully improve them further."
Elliott joined the Cherries for £5,000 from non-league Bashley in 2000 and has scored 37 goals in 257 appearances, while Dublin-born O'Connor arrived on a free from Bohemians later the same year, and has netted 28 goals in 204 games.
A statement on Bournemouth's website read: "Burnley and Steve Cotterill have behaved very professionally throughout and although disappointed to be losing two very talented players, we wish them well and thank them for their service."
