贵格会（英语：Quaker），又称公谊会或者教友派（Religious Society of Friends），是基督教新教的一个派别。

该派成立于17世纪的英国，创始人为乔治·福克斯，因一名早期领袖的号诫“听到上帝的话而发抖”而得名「贵格」（Quaker），中文意译为“震颤者”。但也有说法称在初期宗教聚会中常有教徒全身颤抖，因而得名。该派反对任何形式的战争和暴力，不尊称任何人也不要求别人尊称自己（即不使用“先生”、“女士”、“夫人”头衔，对任何人皆以名字相称呼），不起誓。主张任何人之间要像兄弟一样，主张和平主义和****。该教会坚决反对奴隶制，在美国南北战争前后的废奴运动中起过重要作用。贵格会在历史上提出过一些很进步的思想，其中一部分现在得到广泛接受。

Quakers (or Friends) are members of a group of religious Christian movements which is known as the Religious Society of Friends in Europe, Australia, New Zealand and parts of North America; and known as the Friends Church in Africa, Asia, South America and parts of the US. The movements were originally, and are still predominantly based on Christianity. Members of the movements profess the priesthood of all believers, a doctrine derived from the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity. To differing extents, the different movements that make up the Religious Society of Friends/Friends Church avoid creeds and hierarchical structures. In 2007, there were approximately 359,000 adult Quakers.
