神猪，为道教或民间信仰祭典中，所用牲礼之一，一般指经过刻意增肥豢养的家猪。特别盛行于**。

神猪常见于**新北市三峡区清水祖师庙庆典以及客家地区的义民节庆典。其作用是以该类型猪只屠宰后的大型牲礼，摆于祭典供桌上表达对神祇的敬意。而农家信徒们也会互相饲养神猪，以该神猪体重重量，来一分上下。他们普遍相信，神猪养的越重，甚至于一年一度的神猪竞赛获得胜利，会为未来一年带来好运。

早期，神猪都会整只屠宰，将其内脏拿掉后不加以切割的整只供奉于供桌上，普遍还会在神猪牲礼的嘴巴上，塞个橘子或凤梨，表示吉祥。20世纪中期之后，则有人将其屠宰过后神猪四脚张开，显示庞大。可是不管哪种方式，饲主会将神猪牲礼的猪肉，分给在场信徒、乡众供用。

Shen Dzu or God Pig (Traditional Chinese: 神豬, Simplified Chinese: 神猪; Mandarin Pinyin: shénzhū, Wade-Giles: shen-chu, Hokkien POJ: sîn-tu) are pigs fattened for use in Hakka religious and cultural ceremonies, particularly the Yimin Festival popular in northern ******. Pigs are fattened in a process similar to (and as controversial as) gavage to make them as large as possible in preparation for contests and awards at the festival. Many pigs end up weighing over 800 kilograms and some pigs even weigh more than 900 kilograms, though some growers cheat by force feeding the pigs lead or sand before the weighing. The pig is then ritually killed as a sacrifice to a city god or a local deity, the most popular of these deities being Qingshui Zushi, ironically a deified Buddhist monk.
