A controversial 'ultras' group, the Green Brigade, were responsible for the banner being displayed at Celtic's home ground during their clash with AC Milan last month.
UEFA has banned the displaying of messages of a political or ideological nature in football stadiums.
Its control and disciplinary body has now found Celtic guilty of allowing the "illicit banner" and handed down the fine - the fourth time it has acted against the Hoops in the last two years.
"Clearly it is extremely disappointing that the club must pay another sizeable penalty following the actions of a small minority, particularly given the previous assurances which were made to the club and the widespread understanding of the likely outcome of such actions," a Celtic statement said.
"Regrettably, due to previous charges being brought against the club - again following the actions of a small minority - the fines imposed by UEFA are increasing in scale.
"It goes without saying that such actions must stop now, before the club receives a competitive sanction or one which would affect our supporters attending European matches."
Celtic has already taken action to try to disband the Green Brigade, suspending 128 fans from attending any games and moving 250 season ticket holders out of Section 111 - the traditional seats of the 'ultras'.
That came after seats were ripped up and flares were thrown at Motherwell's home ground, Fir Park, last week.
Celtic's own goalie Fraser Forster narrowly avoided being struck by one of the missiles.
