转轮王（梵文：चक्रवर्तिन्，cakravartin，Chakravartin，巴利语：Cakkavatti），音译为斫迦罗伐剌底、遮迦罗跋帝、遮迦越，又称转轮圣王、轮转圣王，简称轮王，印度宗教中的术语，在印度神话中，当统一世界的君王出现时，天上将会出现一个旋转金轮，作为他统治权力的证明。拥有这个旋转金轮的人，将成为这个世界以及全宇宙的统治者，他将会以「慈悲」与「智能」治理这个世界，开创转轮圣朝（sarvabhauma）。

佛教、耆那教与印度教等，都继承了这个传说。这个称号，在孔雀王朝时代首次出现，为宾头娑罗与阿育王的尊号之一。

Chakravartin (Sanskrit cakravartin, Pali cakkavattin) is an ancient Indian term used to refer to an ideal universal ruler who rules ethically and benevolently over the entire world. Such a ruler's reign is called sarvabhauma. It is a bahuvrīhi, figuratively meaning "whose wheels are moving", in the sense of "whose chariot is rolling everywhere without obstruction". It can also be analysed as an 'instrumental bahuvrīhi: "through whom the wheel is moving" in the meaning of "through whom the Dharmachakra ("Wheel of the Dharma) is turning" (most commonly used in Buddhism and Hinduism).
