The table-topping Foxes won all five of their league matches during the month, scoring 12 goals in the process.
Pearson told the club's official website: "I'm really pleased to have won the award, but I recognise individual accolades such as this as a group achievement, as you can only be a success in a team sport through collective endeavour.
"The players and backroom staff deserve an awful lot of credit for the results we have achieved in the last few weeks, but it's vital now that we focus on the months ahead and achieving our main objective this season, which is promotion."
