Cooper will take up a new role organising UEFA's 50th anniversary events and marketing in 2004.
The move comes just four months after he was sacked following seven years in the top PR role at FIFA.
It was speculated at the time that his departure was part of a staff clear out by president Sepp Blatter, who retained his role following a bitter presidential election campaign in May (PRWeek, 12 July).
Promotional activity surrounding UEFA's 50th anniversary will involve all 52 member states and include a focus on 'the growth of football in Europe' according to Cooper, who added that he was 'looking forward to returning to work in the football environment'.
In a statement announcing Cooper's appointment UEFA CEO Gerhard Aigner said: 'His knowledge and experience of the game of football at world level will help to create a series of events and celebrations that will make UEFA's 50th year in existence in 2004 a memorable one.'
Before joining FIFA Cooper worked for ten years with Swiss-based firm ISL Marketing, first as events manager and later as vice-president of its football division.
Earlier this month UEFA communications boss Mike Lee played down speculation that he was in the running for the vacant chief executive post at the Football Association (PRWeek, 15 November).
