Iowa Highway 99 (Iowa 99) was a state highway in southeastern Iowa. It began in downtown Burlington and generally followed the course of the Mississippi River north to Wapello. Most of the route was a part of the Great River Road. The highway was designated in 1931 and its course remained unchanged until it was removed from the primary highway system in 2003. It was replaced by County Road X99, though around Burlington, it is sometimes referred to as County Road 99.
