Kirk Academy is a K-12 Christian school in Grenada, Mississippi. It is part of the Mississippi Association of Independent Schools (MAIS). In 1966, when the public schools in Grenada County were integrated, some of the most violent acts of the civil rights movement ensued. For five months, violent White mobs congregated outside the schools to forcibly prevent African American students from entering. It was founded in 1966 in response to integration of the public schools and has been described as a segregation academy. As of 2018, all but 11 of the school's 385 students were white.
