Fleming College, also known as Sir Sandford Fleming College, is an Ontario College of Applied Arts and Technology located in Peterborough, Ontario, Canada.

The college was named after the Scottish-born engineer and inventor Sir Sandford Fleming, who is perhaps best known for his contributions to the concept of Universal Standard Time, and who was knighted in 1897 by Queen Victoria.

On 21 May 1965, legislation was introduced in Ontario establishing Colleges of Applied Arts and Technology by then Minister of Education William G. Davis. This historic occasion for education within Ontario marked the beginning of what would become, some 50 years later, a group of 21 Colleges of Applied Arts and Technology and 3 College Institutes of Technology and Advanced Learning.

Sir Sandford Fleming College was subsequently founded in 1967, with David B. Sutherland serving as its first president. Sutherland was the husband of Peterborough's longest-serving mayor, Sylvia Sutherland.

In 2024, facing challenges due to federal policy changes lowering international student enrolment, Fleming cancelled or suspended dozens of programs and these difficulties continued into 2024, leading to laid offs, with the school saying it's been necessary to combat a funding deficit.

The college is governed by a Board of Governors, headed by the President, and executive staff.

The main campus of Fleming College is the Sutherland Campus in Peterborough. Other campuses are located in Cobourg, Haliburton (Haliburton School of Art + Design), and Lindsay (Frost Campus). The college's modern architecture was designed by Ronald Thom.

The Dobbin farm was selected in 1967 for what would later be named the Sutherland Campus. In 1973, the first two phases of the site were opened, and in 1983, the site was named the Sutherland Campus in honour of the college's first and founding president. The Sutherland Campus underwent expansion, including a new on-campus residence in 2002 and a new technology wing in 2003.
