McGinn, a highly experienced coach and registered FA tutor, mentor and assessor, was unveiled a few hours after the departure of former Corinthian-Casuals and Chessington & Hook United boss Howard.
Despite being only four points adrift of the play-off places, the club announced on Thursday morning that Howard had left Colston Avenue following last Saturday’s 7-1 defeat at Ramsgate that brought an abrupt end to a four game unbeaten run and saw the promotion hopefuls drop to 10th spot in the table.
In a statement of the club's website, officials thanked Howard for his efforts at Colston Avenue since taking over at the end of last season in May 2015.
A club statement read: “We have today agreed to part company with Matt Howard. We know that we speak for players, fans and staff in thanking Matt, Luke and his bench staff for their contribution to our club this season.”
McGinn also managed Fulham's deaf side for five years and Carshalton Athletic chairman Paul Dipre urged supporters to back him.
Dipre said: "I am sure that fans, players and staff will join me in supporting Chris in his new role. Chris has coached at the highest level and worked with players such as Dennis Bergkamp, Fabrice Muamba, Jack Wilshere, Bobby Zamora, Raheem Sterling and coaches like Liam Brady, David Platt, Don Howe, Sven Goran Eriksson and Martin Jol.
"His primary brief is to improve the performance of the first team and develop the quality we undoubtedly have in the squad. Chris will also play a part in the Carshalton Athletic development teams from U16s to the reserves to help our ambitions towards home grown players."
