The House of Schleswig-Holstein-Sonderburg-Beck (; Schleswig-Holstein-Beck or Beck for short) is a line of the Schleswig-Holstein-Sonderburg branch of the House of Oldenburg. It consisted of August Philipp, Duke of Schleswig-Holstein-Sonderburg-Beck (1612–1675) and his male-line descendants. Schleswig-Holstein-Sonderburg-Glücksburg (or simply House of Glücksburg), to which several present-day royal houses belong, is the new name of Schleswig-Holstein-Beck.
The members of the line were titular dukes of Schleswig and Holstein, and they were originally not ruling. The line is named after , a manor in Ulenburg, Bishopric of Minden (today Löhne, North Rhine Westphalia). August Philipp bought this manor from the Count of Oldenburg, and he made it his residence.
