33 Ledgelawn Avenue is an historic building in Bar Harbor, Maine, formerly St. Edward's Convent.

It is an architecturally distinguished building designed by local architect Milton Stratton and built in 1917 in the Jacobethan style.

It is a 2-1/2 story brick building, three bays wide, with a cross-gable roof configuration caused by a projecting section at the left half of the front facade.

The other windows of the front are smaller, but also feature diamond paned sashes and stone surrounds with Jacobethan styling.

The Bar Harbor Historical Society was headquartered in the building between 1997 and early 2019, when it moved to the La Rochelle mansion on West Street.
