便雅悯（希伯来语：בִּנְיָמִין / Benyāmîn‎；英语：Benyamin）是雅各和拉结的小儿子（创世记35:18）。

便雅悯出生在从伯特利到以法他的路上，以法他就是伯利恒。拉结生他的时候难产而死，死前给她儿子起名叫便俄尼，意思是「忧患之子」；他父亲却给他起名叫便雅悯，意思是「右手之子」（创世记35:15-18）。他的后代就是便雅悯支派（创世记49:27; 申命记33:12; 约书亚记18:21）。

便雅悯有10个儿子（创世记46:21）。

雅各临终前给他的预言是："便雅悯是个撕掠的狼，早晨吃他所掠夺的，晚上分他所掳获的（创世记49:27）。

Benjamin was the last-born of Jacob's thirteen children (12 sons 1 daughter), and the second and last son of Rachel in Jewish, Christian and Islamic tradition. He was the progenitor of the Israelite Tribe of Benjamin. In the Biblical account, unlike Rachel's first son, Joseph, Benjamin was born in Canaan. In the Samaritan Pentateuch, Benjamin's name appears as "Binyaamem" (Hebrew: בנימין, "Son of my days"). In the Qur'an, Benjamin is referred to as righteous young child, who remained with Jacob when the older brothers plotted against Joseph. Later rabbinic traditions name him as one of four ancient Israelites who died without sin, the other three being Chileab, Jesse and Amram. The Afghan Royal Family is the only Monarchy in the world to claim decent through Benjamin.
