Mid-America Motorplex is a motorsport complex situated in Pacific Junction in the US State of Iowa. The circuit offers both long and short layouts, and was opened in 2002, with a drag strip being added a year later. Mid-America Motorplex is suitable for racecars, motorcycles and karts.

The venue regularly hosts club race meetings, track days and driver training for both two and four wheels. The circuit's asphalt surface is particularly gentle on tires.
