McIntosh County Academy (MCA) is the only public high school in McIntosh County, Georgia, United States. It was formerly known as Darien High School.

In 1794, the city of Darien was given a charter to build a school. In 1820, a branch of the institution was created and classes were held at local churches. The actual school building was built in 1840 on the corner of Adam Street and Rittenhouse Street.

On March 3, 1892, an intentional fire destroyed McIntosh County Academy. The city rebuilt a brick building on top of the remains of the old school in the same year. This was the site of the school for many years, until Darien constructed the new high school off U.S Highway 17.

MCA was built using the one cent ESPLOST (Education Special Local Option Sales Tax).

In 2005, MCA began offering Advanced Placement classes in Calculus, English, US History, Environmental Science, and Art History. These classes are available to juniors and seniors.

MCA did not make AYP until 2007.

MCA was first place in the 2007 GHSA Region 2 GHSGT in English with a 93.7%. The graduation rate rose to third place among the GHSA boards, with 70.6% graduating.
