锡克教（旁遮普语：ਸਿੱਖੀ sikkhī /ˈsɪkːʰiː/ ；英语：Sikhism）是诞生并流行于印度部份地区的宗教。

锡克教是近代宗教（公元十五世纪），是印度教巴克提派的虔信运动（梵天信仰）和伊斯兰教苏菲派一神论的共同基础上产生。创始人和关键人物： 古鲁·那纳克（1469－1539）相信神委托他向人传播新的救赎启示，即所有人都应信奉真神。那纳克及至1708年相继的九大古鲁教导基本的价值观如祈祷、友谊、慈善、顺服、忍耐、谦卑和虔诚，作为通往生活中的灵性之路。

锡克教没有神像，经典是《古鲁·格兰特·萨希卜》。锡克教教徒相信从第一代到第十代古鲁全部具有相同的精神，他们的教训就是启示上帝真名的古鲁话语。这种古鲁精神和话语，从第十代古鲁·戈宾德·辛格以后，就传承给《古鲁·格兰特·萨希卜》。那纳克的追随者自称为锡克（门徒）。“锡克”一词源自梵文「shishya」，意思即「弟子」或「学生」。

Sikhism (/ˈsɪkᵻzəm/), or Sikhi (Punjabi:ਸਿੱਖੀ Sikkhī, pronounced [ˈsɪkːʰiː], from Sikh, meaning a "disciple", or a "learner"), is a monotheistic religion that originated in the Punjab region of South Asia (subcontinental India) during the 15th century. The fundamental beliefs of Sikhism, articulated in the sacred scripture Guru Granth Sahib, include faith and meditation on the name of the one creator, unity and equality of all humankind, engaging in selfless service, striving for social justice for the benefit and prosperity of all, and honest conduct and livelihood while living a householder's life. Although one of the youngest amongst the major world religions, with over 25 million adherents worldwide, Sikhism is the fifth-largest religion in the world.
