“雨中的泪水”（英语：Tears in Rain），也被称为C光束演说（英语：C-Beams Speech）是电影《银翼杀手》中的最后独白，由人造人罗伊·巴蒂（英语：Roy Batty）讲述，该角色由鲁特格尔·哈尔饰演。最终呈现在大银幕上的这段话不是原来剧本中的，在很大程度上是演员哈尔在拍摄前夜即兴创作的。这段独白已经作为“也许是电影史上最动人的死前独白”进入了流行文化中，经常作为科幻作品的代表被引用 。
英语：I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain. Time to die.
英语：I have known adventures, seen places you people will never see, I've been Offworld and back...frontiers! I've stood on the back deck of a blinker bound for the Plutition Camps with sweat in my eyes watching the stars fight on the shoulder of Orion. I've felt wind in my hair, riding test boats off the black galaxies and seen an attack fleet burn like a match and disappear. I've seen it...felt it!
