Celtic fans are celebrating the reform as a small victory, as the club's employees will see their hourly pay increased from $12.54 to $13.18.
The breakthrough comes just one year after club Chairman Ian Bankier said it was "not in the interests" of the club to comply with the living wage.
The club's supporters group, Celtic trust was delighted with the change, while vowing to continuing its fight for the Scottish giant's staff.
“The lowest paid workers have now been paid more than they would have been without this campaign and we are delighted about that.
“We hope you will continue to support us, and that, unless national political developments overtake it, we will soon be able to say that our club is an Accredited Living Wage employer."
The trust also referenced Celtic's founder Brother Walfrid, who started the club in 1887 to address poverty in Glasgow by raising funds for Charity, saying: “We think Brother Walfrid would have wanted that, don’t you?”
With Premiership side Hearts and 380 Scottish employers signing up to the living wage scheme, pressure has increased on Celtic and other Scottish football sides to follow suit.
