Albany Academy for Girls is an independent college-preparatory day school for girls in Albany, New York, United States, enrolling students from preschool (age 3) to grade 12. Founded in 1814 by Ebenezer Foote as the Albany Female Academy, AAG is the oldest independent girls day school in the United States. It is located on the corners of Hackett Boulevard and Academy Road, across the street from its brother school The Albany Academy.

In July 2007, the administrative teams of The Albany Academy and Albany Academy for Girls merged into The Albany Academies. Both schools bring with them deeply treasured values of community, tradition and purpose to the newly formed institution known as The Albany Academies. However, The Albany Academy and Albany Academy for Girls continue to grant their own diplomas.

The Board of Trustees announced that The Albany Academy and Albany Academy for Girls would merge into The Albany Academies in July 2007. Single-gender education will continue under the present form in Lower and Middle Schools, while Upper School students may continue to cross-register for coed classes and certain extracurricular activities. On July 1, 2009, the Board of Trustees announced the appointment of Douglas M. North AA'58, President of Alaska Pacific University, to the position of Head of School of The Albany Academies, effective July 2010.

The Albany Academies are accredited by the New York State Association of Independent Schools and recognized by the Regents of the State of New York. The Albany Academies are a member of the following associations: the College Board, the Cum Laude Society, the National Association of Independent Schools, the Educational Records Bureau, the Capital Region Independent Schools Association, the Association of Boys' Schools, the Secondary Schools Admission Test Board, and the New England Prep School Athletic Association.
