The Magpies manager guided his side to three wins from three last month, with victories over Watford, AFC Bournemouth and Burnley lifting United up the table.
Benítez was nominated for the award alongside Manchester City’s Pep Guardiola, Liverpool’s Jurgen Klopp, Tottenham’s Mauricio Pochettino.
The list of nominees was completed by Everton’s Marco Silva and Huddersfield Town’s David Wagner.
And after a public vote, the Newcastle boss was given the award to mark his team’s 100 per cent record in November.
“It’s always good to win trophies,” said Benítez. “Obviously I would like to win more manager of the months, as it would mean that we are in a better position in the table. It’s always positive, it’s always good, and it’s good also for the staff and everybody who is helping you.
“Everybody has to be congratulated for this kind of thing. Always, in any club, it’s not just the manager – it’s a lot of people behind the scenes who are doing a great job.”
