Concordia Academy is a Christian high school (Grades 9–12) in Roseville, Minnesota, United States.

Established in 1893, it is a Christian high school owned and operated by the Lutheran High School Association of St. Paul and affiliated with the Lutheran Church–Missouri Synod.

Concordia Academy originated in 1893 as the high school portion of Concordia College (now University) in St. Paul, Minnesota.

In 1967, the academy merged with St. Paul Lutheran High School, which had been founded in 1959.

St. Paul Lutheran had occupied the building at 2400 North Dale Street in Roseville since 1962; that location became the site of the merged schools.
