法律博士（英语：Juris Doctor，缩写为J.D.）是美国法律教育体系中的「专业博士学位」（professional doctorate degree），也是“第一专业研究生学位”（first professional graduate degree）。。该学位的学业完成时间通常为3年（兼职修读则需4年），申请者需要具备大学本科学历。设立其的目标是为有志从事法律工作的人提供学术和专业的训练。美国大学本科不设法律学位，法律是研究生阶段法学院的专业教育，授予完成这段教育的人「法律博士」学位。大多数州，「法律博士」学位是参加律师资格考试、取得律师执照的必要条件，不过，虽称作“博士”，这不是一般所指的“博士研究学位”（哲学博士，Ph.D.）。
