Brother of former world super-middleweight boxing champion Steve, Collins
has signed a two-year contract, beating Peter Beardsley and Wes Saunders to
the post.
It's believed his success in the Irish game with last season's double winners Bohemians earned him the job.
The Cabra native also oversaw away victories for Bohemians over Aberdeen
and Kaiserslautern in Europe last season.
Collins replaces Ian Atkins, who departed for Cardiff City at the end of last season.
