Lessebo Municipality () is a municipality in eastern Kronoberg County in southern Sweden, where the town Lessebo is seat.
The nationwide local government reform of 1971 saw the creation of the present municipality, when three surrounding municipalities were amalgamated with the market town (köping) of Lessebo (itself instituted in 1939)
In its history, Lessebo Municipality still honours the Swedish emigration in the late 19th century, whereby many poor farmers from Sweden – many of them from Småland – emigrated to the U.S.. When Vilhelm Moberg wrote his acclaimed novels about this time, he located his main characters' home to the parish of Ljuder in eastern Lessebo Municipality. An honorary Walk of the Emigrants also stretches through the municipality and continues to Karlshamn in the south.
