The Colombia–Peru War, also called the Leticia War, was a short-lived armed conflict between Colombia and Peru over territory in the Amazon rainforest that lasted from September 1, 1932, to May 24, 1933. In the end, an agreement was reached to divide the disputed area between both countries.

The conflict was rooted in the Boundary Treaty of March 24, 1922, which transferred the Leticia district to Colombia, giving Colombia access to the Amazon river. The district was mostly inhabited by Peruvians, which fueled grievances among Peruvians and led them to seek to modify the treaty.
