双学士（英语：double degree）又作双学位。「并非双联学制」，亦非第二专业。 相同的，也有双硕士，双博士。

由来已久，由在校生书面申请，并由教务人员审核通过即可修习。通常会使毕业年份延长，造成延毕的现象。但若有一专业已修满学分，即可领取其专业学位。

A double degree program, sometimes called a dual degree, combined degree, conjoint degree, joint degree, or simultaneous degree program, involves a student's working for two different university degrees in parallel, either at the same institution or at different institutions (sometimes in different countries), completing them in less time than it would take to earn them separately. The two degrees might be in the same subject area (especially when the course is split between countries), or in two different subjects.
