Pusan National University (PNU), also called Busan National University, is one of ten national Universities in South Korea. Located mainly in Busan (or Pusan), the university's English name is a translation of its former Korean name, "Gungnip Pusan Daehakgyo" , but has since dropped "national" from its Korean moniker.

It was founded as a two-year college in 1946 and became a regular four year university in 1953.

This University is known as the second best national university in South Korea, after Seoul National University. It is famous for its Engineering departments including Mechanical Engineering.
