The Nanpū (南風, English: "south wind") is a limited express train service in Japan operated by Shikoku Railway Company (JR Shikoku), which runs from Okayama to Kōchi.

Trains are formed of 3-car or 2+3 car sets of 2700 series DMUs, and sometimes are coupled with Shimanto services between Tatotsu or Utazu and Kochi.

Okayama - Tadotsu - Awa-Ikeda - Kōchi Nanpū services began as a semi express from the former Takamatsu Sanbashi Station to Kubokawa in Shikoku from 1 October 1950.

From 1 October 1968, however, the name was used for express trains operating in Kyushu between Beppu and Nishi-Kagoshima.

From 15 March 1972, the name returned to Shikoku, for limited express trains operating between Takamatsu and Nakamura.
