The Department of State Lands (DSL), one of the oldest agencies of government of the U.S. state of Oregon, is principally responsible for the management of lands under state ownership, as its name implies.
 Unlike most other department-level state agencies, it is not headed by a sole elected official, but is the administrative arm of the Oregon State Land Board.
 Although established by the Constitution, subsequent statutes have added to its duties and authority, and include some provisions relating to its conduct.
 In addition to managing state-owned lands, the Board through the Department is responsible for the Common School Fund, off-shore lands and coastal estuarine tidelands, submerged and submersible lands of the navigable waterways, unclaimed property, estates with no heirs, and additional functions assigned by the Oregon Legislative Assembly from time to time.
 The Board decides cases, adopts rules, issues policy statements, and approves DSL recommendations.
