Vigil Games was an American game development company owned by THQ. It was formed by comic artist Joe Madureira and David Adams in 2005.

Although much of THQ's assets were sold in an auction as part of bankruptcy hearings, Vigil itself received no bids. In a letter written by THQ's CEO Brian Farrell, it was stated that Vigil would remain part of the Chapter 11 case and that THQ would still try to find a suitable buyer for the properties not sold in the auction, but that there would be immediate job losses in the affected entities.[2]

At the time of bankruptcy, Vigil was developing Warhammer 40,000: Dark Millennium Online.
