The Old Monroe County Courthouse Museum in Monroeville, Monroe County, is the centerpiece of a five-site group referred to collectively as the Monroe County Heritage Museum. The courthouse's most significant claim to fame is its inspiration for the fictional courthouse in Harper Lee's novel To Kill a Mockingbird. In addition to housing four permanent exhibits and serving as the model for the courtroom featured in the film version of Lee's novel, the courtroom is the setting for the second act of a popular stage production of the novel that is performed annually in April and May in Monroeville.

The courthouse was in use until 1963, when a newer building was constructed in the same town square. A small museum was opened with limited hours in 1968. Large numbers of townspeople called for the building to be razed to make room for downtown parking in the 1970s; however, with the guidance of probate judge Otha Lee Biggs, a small group of people secretly put the building on the National Register of Historic Places, preserving it for posterity. In 1989, a Blue Ribbon Committee was formed to raise funds for restoration, with private donors contributing more than $2.5 million for work done on the building between 1991 and 2002. Periodic restoration work continues on the building today.
The four permanent exhibits in the museum include one on Harper Lee herself and one on her childhood friend and fellow author, Truman Capote. In addition to the annual production of To Kill a Mockingbird, the museum presents a number of events and educational programs centered on the novel and on the history of Monroe County, as well as related to Truman Capote.

The other sites that make up the Monroe County Heritage Museums are Rikard's Mill Historical Park, the Alabama River Museum, the Hybart House Museum and Cultural Center, and the Old Bethany Baptist Church.
