Queens Park Rangers fan Bill Power has joined the Loftus Road board after pumping £200,000 into the club.
Power becomes the third supporter to be offered a directorship after injecting cash into QPR, following Harold Winton and Kevin McGrath.
"It's a dream come true to join the board and I'm really pleased," Power told BBC Sport.
"I'm from White City and have supported Rangers all my life. To be able to help QPR in this way means a lot to me.
"I haven't been part of any of the bids to take over the club and I don't have any agenda other than wanting to help the club as best I can."
Meanwhile, Rangers have formally completed the signing of French forward Eric Sabin and are giving a trial to Australian midfielder Michael Kathopoulis.
