沙嗲（印尼语：Sate，马来语：Satai），又名沙嗲串烧、沙嗲串，是一种东南亚的烤肉串，通常肉以酱汁先腌过再烤。沙嗲的食材可能是切片或切块的鸡肉、羊肉、牛肉、猪肉、鱼，其它肉类，或豆腐。沙嗲虽然经常使用竹签串肉，但比较正统的是以椰子树叶的梗串肉。沙嗲通常以木材或木炭烤，然后吃时可以再加上各种辛辣的沙嗲酱调味。

沙嗲是起源于印度尼西亚，几乎在印尼的任何地方都可以吃到沙嗲，它已成为印度尼西亚的国菜。沙嗲在许多其他东南亚地区，如泰国、马来西亚、新加坡、文莱、香港、菲律宾、甚至以前殖民印尼的荷兰及同为荷兰前殖民地的苏里南都很受欢迎。

Satay (/ˈsæteɪ/, /ˈsɑːteɪ/ SAH-tay), modern Indonesian and Malay spelling of sate, is a dish of seasoned, skewered and grilled meat, served with a sauce. Satay may consist of diced or sliced chicken, goat, mutton, beef, pork, fish, other meats, or tofu; the more authentic version uses skewers from the midrib of the coconut palm frond, although bamboo skewers are often used. These are grilled or barbecued over a wood or charcoal fire, then served with various spicy seasonings.
