半伯拉纠主义（英语：Semipelagianism）是基督教神学和救赎论中有关拯救思想的一个流派。半伯拉纠主义认为，人性和上帝被恢复到一个正确的关系。此观点与更早的伯拉纠主义相反。后者教导说，人被看做是可以自身拯救，因此伯拉纠主义被视为异端。半伯拉纠主义最初是为了妥协伯拉纠主义和一些诸如圣奥古斯丁的教父的教导（圣奥古斯丁称，人只能凭借上帝的恩典才能进入天国）。在半伯拉纠主义中，信心的增长是上帝的功劳，虽然最初的信心是基于自由意志，而恩典只是在后来伴随。在公元529年的奥朗日会议（Second Council of Orange）上被天主教定为异端。

Semipelagianism is a Christian theological and soteriological school of thought on salvation; that is, the means by which humanity and God are restored to a right relationship. Semipelagian thought stands in contrast to the earlier Pelagian teaching about salvation (in which man is seen as effecting his own salvation), which had been dismissed as heresy. Semipelagianism in its original form was developed as a compromise between Pelagianism and the teaching of Church Fathers such as Saint Augustine, who taught that man cannot come to God without the grace of God. In Semipelagian thought, therefore, a distinction is made between the beginning of faith and the increase of faith. Semipelagian thought teaches that the latter half - growing in faith - is the work of God, while the beginning of faith is an act of free will, with grace supervening only later. It too was labeled heresy by the Western Church in the Second Council of Orange in 529.
