In der Maur (also written as In der Mauer, Indermaur, Indermauer) is a Swiss family. Throughout the Middle Ages and Renaissance, members of the family held political offices in Berneck, St. Gallen. The In der Maur von Berneck family were first granted a coat of arms in 1478, when Hermann In der Maur was appointed as the Ammann of Berneck of the Abbot of St. Gallen. Members of the family also served as Imperial tax collectors and as clerks of the Court of Berneck. The first member of the family to hold the position of Ammann in Berneck was Ulrich In der Maur in 1435.
A member of the Bernecker branch, Hans Indermaur, settled in Rheineck in 1590, where his descendants were granted fiefdoms. The Indermaur von Rheineck family were granted a coat of arms in 1685, first used by Johann In der Maur, and members of this family served as magistrates and clerks of the Court of Rheineck.
A cadet branch of the family based in South Tyrol, In der Maur auf Strehlburg und zu Freifeld, was elevated to the lower nobility in Kurtatsch an der Weinstraße by Rudolf II, Holy Roman Emperor in 1601. They were previously granted coats of arms in 1479, 1491, and 1586.
