《统天历》是中国古代历法,南宋杨忠辅编纂,属于阴阳历。
宋宁宗庆元五年(1199年)历成,帝赐名为《统天历》,并于是年实施。
《统天历》计算出1太阳年为365.2425日,1朔望月为29.530594日,这一数值取代了祖冲之测量的365.2428日。与公历的1太阳年的数値相同。清人梅文鼎称「宋历莫善于纪元,尤莫善于统天」。然而,嘉泰二年(1202年)五月甲辰朔日蚀,《统天历》预推时刻比实际天象早了一个半时辰。《统天历》因推测日蚀不验,仅使用到开禧三年(1207年)。大理评事鲍浣之曾对《统天历》虚立上元一事大加挞伐,谓「以是而为术,乃民间之小历。而非朝廷颁正朔、授民时之书也。」于是,鲍浣之又造《开禧历》取代《统天历》。
