This was Rennes's fifth appearance in the final, having won the cup in 1965 and 1971, and finishing as runners-up in 1922 and 1935. It was Rennes's first final playing under their new emblem and name having achieved the previous honours under the Université Club emblem. This was Guingamp's second appearance in the final having appeared in the 1997 edition of the final, losing to Nice on penalties.
This was the first final since 1956 where both clubs were based in the same region, both clubs being based in Bretagne.
Rennes was designated as the home team and wore their original red and black kit. Due to Guingamp having similar colours, both home and away, they unveiled an all white kit for the final.
The opening of the 2009 final of Coupe de France at Stade de France, seeing La Garde Républicaine performing Tri Martolod and Bro Gozh ma Zadoù, the former being made famous by Breton musician Alan Stivell and the latter being the national hymn of Brittany.
The first half of the 91st final of the Coupe de France was pretty equal early on, but it was Guingamp who attacked early on producing a great fingertip save from Nicolas Douchez after the Brazilian Eduardo got a left-footed chance on goal after dislodging Rod Fanni in the 12th minute. This was followed up by a long range chance from midfielder Lionel Mathis, however, Douchez didn't require a save as it was just wide left. Rennes were primarily being held to only long range shots, however, that didn't stop Moussa Sow from testing Guillaume Gauclin in the 23rd minute, producing a shot that was just wide, but was enough of a concern for Gauclin to dive for it. The best chance of the first half would come in the 31st minute when the Nigerian Wilson Oruma cross into the box and found an open Richard Soumah who forced a tremendous save out of Douchez. Rennes responded in the 40th minute with Jérôme Leroy taking an unexpected shot from almost 30 metres out. The shot got past the Guingamp keeper, but struck the post going out of play.
The final of Coupe de France, ironically a Breton derby, saw wide use of Breton symbols, notably the Gwenn-ha-du.
The second half began with a quick attack from Rennes. Capitalizing on a Guingamp turnover, Rennes started a counterattack led by Moussa Sow. Their chance, taken by Leroy, was shot straight at the Guingamp keeper. In the 53rd minute, Rennes would almost get the first goal of the match again when Leroy found Sow. However, Rennes, for the second time in the match, hit the post after Sow's shot beat the keeper easily. Leroy and Sow would be involved in another chance again from Rennes in the 65th minute. After a cross into the box, Sow attempted an overhead kick, but instead knocked the ball into the air and into the path of Leroy, who again blew a chance, sending the ball into the stands, despite being about 10 metres from goal. Rennes would finally get their goal following a free kick into the box. The ball went through everyone except the American Carlos Bocanegra, who headed the ball past Gauclin, giving Rennes a 1–0 lead. However, within minutes, Guingamp would respond. Following a Felipe Saad cross into the box, the ball landed at the feet of the Swede Peter Hansson and redirected right into the path of Eduardo, who took the chance to even the match at 1–1. Ten minutes later, Eduardo would strike again, when, after a scramble in the box, he found the ball at his feet and proceeded to take a driven right-footed shot that ran right under Douchez to give the Ligue 2 side a 2–1 lead. The goal eventually turned out to be the winner, giving the second division side their first Coupe de France trophy in their history. Their victory also earned them an appearance in the 2009–10 UEFA Europa League.
