Aílton José Almeida (born 20 August 1984 in Hematita, Santa Maria de Itabira, Minas Gerais), simply known as Aílton (Brazilian Portuguese: ), is a Brazilian footballer who plays as a forward for Örgryte IS.
He moved to F.C. Copenhagen from Swedish Örgryte IS on 1 January 2007 for 22 million Danish kroner, which by then was transfer record for a Danish club. Both F.C. Copenhagen and Brøndby IF struggled for Almeida's signature, but after some hesitation from Brøndby IF, he ended up at F.C. Copenhagen.
Scoring in his only second game for F.C. Copenhagen against Brøndby IF in one of the New Firm matches, he was considered a new star and a start of a new era for the club, which for many years had suffered from the lack of goals from the strikers, however, he did not manage to follow up his performance, and was subsequently placed on the bench as a substitute. On 15 April 2007, Ailton scored on a bicycle kick in F.C. Copenhagen's 4–2 win over OB, which led to many people thinking he's breakthrough finally was about to come, but yet again, and had to see himself become a substitute.
