2019-20シーズンのボストン・セルティックスは、セルティックスの全米バスケットボール協会(NBA)においてフランチャイズ74年目のシーズン。2019年7月6日、元シャーロット・ホーネッツのオールスター選手、ケンバ・ウォーカーを獲得した。また、FAからポートランド・トレイルブレイザーズのセンターのエネス・カンターも獲得した。

3月11日にユタ・ジャズのルディ・ゴベールらが新型コロナウイルスの陽性反応を示したため、リーグ関係者によって感染防止を理由にシーズンは中断となり、3月19日にはマーカス・スマートがCOVID-19の陽性であったと発表された。6月4日、セルティックスはシーズン再開となるNBAバブルの出場権を獲得した。
