学校旅行，又称修学旅行、户外教学，是中小学教育的一环，指教职员带领学生集体行动、合宿的旅行活动。

日本的修学旅行最早为1882年（明治15年）栃木县第一中学校（现・栃木县立宇都宫高等学校）的学生由教师带领参观「第二回勧业博覧会」、1886年（明治19年）东京高等师范学校（现在的筑波大学）的「长途远足」创造长达11天的修学旅行记录。

A field trip or excursion is a journey by a group of people to a place away from their normal environment. When done for students, it is also known as school trip in the UK, New Zealand; and school tour in Ireland.

The purpose of the trip is usually observation for education, non-experimental research or to provide students with experiences outside their everyday activities, such as going camping with teachers and their classmates. The aim of this research is to observe the subject in its natural state and possibly collect samples. Field trips are also used to produce civilized young men and women who appreciate culture and the arts. It is seen that more-advantaged children may have already experienced cultural institutions outside of school, and field trips provide a common ground with more-advantaged and less-advantaged children to have some of the same cultural experiences in the arts.
