The CNO Financial Indianapolis Monumental Marathon is a road marathon in downtown Indianapolis, Indiana, held on a Saturday in early November. It is organised by Beyond Monumental and run together with a half marathon and a 5K. The marathon starts at 8:00 am, with the start and finish areas on Maryland Street, a block from the Indiana Convention Center. The organisers describe a fast and flat course that winds through downtown and a number of historical neighborhoods and cultural districts, and it passes the Heslar Naval Armory just after mile 20. The time limit is seven hours, a minimum pace of 16 minutes per mile, and the finish line closes at 3:30 pm. The marathon was first held in 2008, when just over 1,100 runners finished, and in 2025 it had 6,674 finishers. Since 2016 it has been the only full fall marathon in Indianapolis. The course records are 2:12:29 for men (Joseph Whelan, 2025) and 2:31:49 for women (Lindsey Bradley, 2024).

The Monumental Marathon was established by Carlton Ray in 2008. Just over 1,100 runners finished the first race, and almost 2,000 finished the next year. Runner's World named it one of the nine best new US marathons in 2014.
Joseph Whelan won the 2025 race in 2:12:29 by the organiser's count, the men's course record. The previous fastest winning time on the course list was Lyle O'Brien's 2:15:39 in 2023.
