It follows on from the Livi manager landing December’s award.
The West Lothian juggernaut went through the month unbeaten, defeating Hibs, Ross County and Kilmarnock, while earning two draws with Celtic and one with Aberdeen.
In the Betfred Cup, Livi reached the final after beating St Mirren 1-0 at Hampden Park.
Martindale donated his December manager of the month award to be auctioned by local mental health group, Kick Mental Health, raising nearly £3,500.
He said: “I was delighted we received this award the first time around but over the moon that we have managed to pick the award up for January 2021 also. It's all down to everyone at the club but I'm more than delighted to accept this trophy and it's a trophy I will look forward to giving a home in my house.
“The last trophy has raised just under £3.5K which is phenomenal, and I'm delighted that the money raised will go to the Kick mental Health Group. What an unbelievable effort by everyone that bought a ticket, the generosity shown has been incredible. It shows you the power of football as there were fans from all over who purchased tickets. But I would like to keep this award long term.
“I have to thank everyone who has voted for me to receive this award again, it goes without saying, there is no chance I would be picking this award up if it wasn't for the players and staff at the club! We are all in this together and I think that has been shining through over the last 14/15 games. A big thanks to you all.”
Livingston unbeaten run under Martindale which stretched to 14 games came to an end at the weekend as St Johnstone won 2-1 at the Tony Macaroni Arena.
Colin Matthews, CEO of Glen’s owner the Loch Lomond Group, said: “Livingston has been in incredible form ever since David Martindale took charge of the club, so it will likely come as little surprise that he has been named the Glen’s Manager of the Month for the Scottish Premiership for a second month running. My congratulations to him, his colleagues and his squad on another well-deserved award.”
