Jun-iti Nagata (長田 潤一, Nagata Jun'ichi, 1925 - 6 November 2007) was a Japanese mathematician specializing in topology.

In 1956, Jun-iti Nagata earned his PhD from Osaka University under the direction of Kiiti Morita. He was the author of two standard graduate texts in topology: Modern Dimension Theory^[1] and Modern General Topology.^[2] His name is attached to the Nagata–Smirnov metrization theorem, which was proved independently by Nagata in 1950 and by Smirnov in 1951.

Nagata became a professor emeritus at both Osaka Kyoiku University, where he taught for 10 years, and Osaka Electro-Communication University, where he taught for 5 years.
