Matsudo Sports Park, park in Matsudo, Japan

Matsudo Sports Park is a public sports complex in Matsudo, Chiba Prefecture, with a 400-meter urethane athletics track certified as Japan Association of Athletics Federations third-class and seating for about 2,000. Its baseball field measures 90 meters down the lines and 120 meters to center, seats about 3,300 and has night lighting. The grounds also hold a gymnasium, a budokan, a sumo ring with 200 seats, outdoor 50-meter and children's pools, and a children's playground.

Facilities opened in stages: the budōkan and outdoor pools in 1971, the baseball field in 1972, the gymnasium in 1974 and the athletics track in 1976. Floodlights were added to the baseball field in 1989. In 2005 the site was proposed as a new location for Matsudo City Hospital, but the plan was withdrawn in 2009 and the move itself later frozen. In 2010 online booking began and the park hosted fencing at the Chiba National Sports Festival.

The park's name is written 松戸運動公園, and its sumo ring (353.7 m², seating 200) is one of the few full-scale ones in the city. The gymnasium doubles as a ballot-counting station during elections, and in spring cherry-blossom viewers fill the grounds. Facility bookings are made over the internet.

The park is about 12 minutes on foot from Matsudo-Shinden Station on the Keisei Matsudo Line; from JR Kitamatsudo Station take a Keisei bus and get off at "Undo-koen-mae". Facilities can be booked online, and the site is designated as an evacuation area and helicopter landing spot in disasters.

The park has a full-scale sumo ring with a 353.7 square metre site and room for 200 spectators, unusual for a municipal sports park. The gymnasium also serves as a ballot-counting venue during city elections. In 2010 the park hosted fencing at the Yume Half Island Chiba National Sports Festival.
