The Indianapolis-Carmel, IN, Metropolitan Statistical Area is the 33rd largest Metropolitan Statistical Area (MSA) in the United States. It was originally formed by the United States Census Bureau in 1950 and consisted of the Indiana county of Marion.

It is now the primary MSA of the Indianapolis-Anderson-Columbus, IN Combined Statistical Area which also includes the Anderson, IN, MSA of Madison County, Indiana, the Columbus, IN, MSA of Bartholomew County, Indiana, and the Micropolitan Statistical Areas of Crawfordsville, IN (Montgomery County, Indiana), New Castle, IN (Henry County, Indiana), and North Vernon, IN (Jennings County, Indiana).
