The Stabler-Leadbeater Apothecary Shop/Museum is a historic apothecary's shop in Alexandria, Virginia, that has been preserved as a museum. During its working life, it was owned by generations of a Quaker family. Eventually, a dramatic decline in sales during the Great Depression forced the shop to close its doors. Almost immediately, in 1939, it was reopened as a museum. Today, most of the artifacts inside the shop are authentic and date to its closing. The building was added to the National Register of Historic Places in 1982, and designated a National Historic Landmark in 2021.
