Re·ac·tor is the eleventh studio album by Canadian folk rock musician Neil Young, and his fourth with American rock band Crazy Horse, released in November 2, 1981. The album marked Young's first use of the Synclavier, which would be featured heavily on the subsequent albums Trans (1982) and Landing on Water (1986). The album features the Serenity Prayer on its back cover ("'Deus dona mihi serenitatem accipere res quae non possum mutare fortitudinem mutare res quae possum atque sapientiam differentiam cognoscere'" – "God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference").
