Mercy Academy, in full, The Academy of Our Lady of Mercy, is an all-girls Roman Catholic high school in Louisville, Kentucky that opened in 1885 and is sponsored by the Sisters of Mercy. In 1869, the first Sisters of Mercy in Louisville arrived from their community in St. Louis to run a struggling Federal Marine Hospital. They began a teaching ministry. By 1872, they had established St. Catherine Academy, and in 1885, they conferred the first high school diplomas under the name of The Academy of Our Lady of Mercy. The high school program continued to grow until a new facility was needed. The Sisters opened a new Academy building at 1176 East Broadway in 1901, where it was to remain until 2007.
