The Italian has made an instant impact since arriving at Stamford Bridge following the end of Euro 2016.
In his first season in the Premier League he spearheaded a dominant title challenge, with Chelsea eventually winning the title by seven points over closest rivals Tottenham.
And he has been honoured with the prestigious LMA award at the Association's annual dinner, determined by votes from managers across the league pyramid.
It is the second time in as many years that an Italian has taken the gong, with Claudio Ranieri winning last time round in recognition of his work taking Leicester City to a thrilling title.
It completed a double night of celebration for Conte, who also won the Premier League Manager Year of the Prize earlier in the evening.
Chelsea took a mammoth 93 points over their 38 games, losing just five times over the course of the season to stroll to Premier League success.
Brighton and Hove Albion's Chris Hughton received the prize in the Championship as he took the Seagulls back to the top flight for the first time in 34 years.
There were also awards for Paul Cook of Portsmouth and Sheffield United's Chris Wilder, who won in League Two and One respectively for 2016-17.
Lincoln City's Danny Cowley, meanwhile, received a Special Achievement award after the non-league side battled through to the quarter finals of the FA Cup in a thrilling run that was eventually ended by Arsenal as well as winning the National League.
