Lackenbach (Hungarian: Lakompak, Croatian: Lakimpuh) is an Austrian municipality in the District of Oberpullendorf, Burgenland.

From the 18th century, Lackenbach belonged to Prince Esterházy's Siebengemeinden where the Jews had their own autonomous administration.

After the end of the First World War, the western border area of Hungary was awarded to Austria by the Treaties of St. Germain and Trianon.

The inmates, mainly Romani from Burgenland, were made to do forced labor and, starting in 1943, were partially deported to Auschwitz-Birkenau where they were murdered.

The mandate assignments in the Municipal Council (19 seats) are SPÖ 11, ÖVP 8, FPÖ 0, Grüne 0, and other lists 0.
