Daewi or taewi is a military rank in both South Korean and North Korean militaries.

In the South Korean military, daewi is a Korean military rank used in the South Korea military. The rank is considered equivalent of a captain in many Western armies and air forces and to a full lieutenant in many navies.

In the North Korean military, it corresponds to an army or air force senior captain, a rank between U.S. captain and major. A daewi in the North Korean Navy would correspond, equivalently, to a senior lieutenant, a rank between U.S. Navy lieutenant and lieutenant commander.
