校车是用来运送学生往返学校的一种交通工具。是集体运输工具之一，收月费或年费。可能是校方聘请司机自行经营，或是与地区性的公车业者签约租用的学生专车。

A school bus (also called Schoolbus ) in North America is a type of bus specifically designed, manufactured and used for student transport: carrying students to and from school, home, and school events. School buses provide an estimated 10 billion student trips every year. Each school day in 2013, nearly 468,000 school buses transported 28.8 million children to and from school and school-related activities; over half of the United States K–12 student population is transported by school bus.
