The Grand Lodge of the Republic of Liberia is a fraternal organization based on the principles of Prince Hall Freemasonry. Prior to 1980, its membership tended to consist of Americo-Liberians and it was influential within the ruling True Whig party from its founding until the coup of Samuel Doe in 1980, when much of its senior leadership was killed and the new military regime banned masonic activities in the country.

Prince Hall Freemasonry is a branch of North American Freemasonry for African Americans founded by Prince Hall on September 29, 1784. There are two main branches of Prince Hall Freemasonry: the independent State Prince Hall Grand Lodges, most of which are recognized by State grand lodges, and those under the jurisdiction of the National Grand Lodge. Prince Hall Freemasonry is the oldest and largest predominantly African-American fraternity in the United States.
