Allen County War Memorial Coliseum is a 13,000-seat multi-purpose arena located in Fort Wayne, Indiana, United States, near present-day Johnny Appleseed Park.

In 2002, an extensive $35 million renovation and expansion raised the Allen County War Memorial Coliseum's roof by 41 feet (12 m), thus increasing the arena's seating capacity to 10,500 for hockey or music concerts and 13,000 for basketball.

More recently, the University of Notre Dame hosted the 2010 NCAA Division I men's ice hockey tournament Midwest Regional at Memorial Coliseum.

Within the same complex as the arena, the Allen County War Memorial Coliseum Exposition Center contains 108,000 square feet (10,000 m2) devoted to hosting substantial trade shows, banquets, graduation ceremonies, concerts, truck and tractor pulls, and wrestling matches, with the capability of seating 7,500 guests.

It has allowed drivers from major racing series to participate: Dave Darland, Tracy Hines, J. J. Yeley, Bryan Clauson Sammy Swindell; with NASCAR, USAC and IndyCar champion Tony Stewart having the most feature wins at 9.
