Lenzburg Castle () is a castle located above the old part of the town of Lenzburg in the Canton of Aargau, Switzerland. It ranks among the oldest and most important of Switzerland. The castle stands on the almost circular castle hill (altitude: 504 m), which rises approximately over the surrounding plain but is only about in diameter. The oldest parts of the castle date to the 11th century, when the Counts of Lenzburg built it as their seat. The castle, its historical museum and the castle hill with its Neolithic burial grounds are listed as heritage sites of national significance.Swiss inventory of cultural property of national and regional significance (1995), p. 410.
