Deputy Marshal of the Sejm of the Republic of Poland (Polish: Wicemarszałek Sejmu RP) is a person elected to preside over Sejm (Polish lower chamber of parliament) sessions when the Sejm Marshal is not presiding.

Throughout the course of the Third Republic, there have always been several Deputy marshals, usually elected from some or all of the various parliamentary caucuses, rather than from the Government majority (although governing parties always have a majority in the Sejm Presidium, which is composed of the Marshal and Deputy Marshals).
