约瑟夫·拉弗森（Joseph Raphson，1648年－1715年）是英格兰数学家，和牛顿都提出过后来被人称为的牛顿-拉弗森方法，他的一生鲜为人知，甚至他的出生和逝世的日期都难以确定，数学史的学家Florian Cajori曾提供出的约瑟夫·拉弗森的大致日期为1648年－1715年。

Joseph Raphson was an English mathematician known best for the Newton–Raphson method. Little is known about his life, and even his exact years of birth and death are unknown, although the mathematical historian Florian Cajori provided the approximate dates 1648–1715. Raphson attended Jesus College at Cambridge, graduating with an M.A. in 1692. He was made a Fellow of the Royal Society on 30 November 1689, after being proposed for membership by Edmund Halley.
