The Lord High Constable (Swedish: riksmarsk or only marsk) was a prominent and influential office in Sweden, from the 13th century until 1676, excluding periods when the office was out of use. The office holder was a member of the Swedish Privy Council and, from 1630 and on, the head of the Swedish Council of War. From 1634, the Lord High Constable was one of five Great Officers of the Realm.
