The NCAA Division III men's swimming and diving championships are contested at an annual swim meet hosted by the National Collegiate Athletic Association to determine the individual and team champions of men's collegiate swimming and diving among its Division III members in the United States.

Since 1982, it has been held concurrently with the Division III women's championships.

The most successful program has been Kenyon, who have won 34 national titles.

Kenyon's 34 titles are the most by any collegiate program in one sport at any NCAA division.

Furthermore, Kenyon's thirty-one consecutive titles (1980 until 2011), is also a record across all three divisions.
