比司吉（英语：biscuit）在美国英语中是以泡打粉或小苏打取代酵母作为化学膨松剂制成的小面包。它的外面皮烤得焦黄坚脆，内里蓬松而绵软，类似于英国英语的司康饼或昔德兰群岛的班诺克面包。比司吉面包、苏打面包和玉米面包等烘焙面食由于发酵制程不耗费时间，一般合称为「速发面包」（quick breads）。

A biscuit in the United States and parts of Canada, and widely used in popular American English, is a small baked good with a firm browned crust and a soft interior. They are made with baking powder or baking soda as a chemical leavening agent rather than yeast. They are similar to British scones or the bannock from the Shetland Isles.
