Momijiyama Park, Urban park in Sugitsumachō, Japan

Momijiyama Park is a park in Sugitsumachō, Fukushima, occupying the former outer garden of the second enclosure of Fukushima Castle. A pond forms its centre, and the layout of the old garden, with its tea house and artificial hills, survives almost unchanged. It lies east of the Fukushima Prefectural Office and west of the governor's residence, and a path leads down to the bank of the Abukuma River.

The park was established in 1933 near Fukushima Castle, becoming a central green space for the district. This location near a historic landmark shaped its role in the neighborhood.

The garden was modelled on the Yatsuhashi Iris Garden in old Mikawa Province (now Aichi Prefecture), though irises are no longer planted in the old garden area. It hosts the shrine's annual festival and events organised by local residents. The Momijiyama-dōri road beside it takes its name from the park and was opened in its present form in 1882 by Governor Mishima Michitsune.

The park sits between the Fukushima Prefectural Office to the west and the Governor's Residence to the east, in Sugitsumachō. From the grounds a path leads down to the riverbank on the left bank of the Abukuma River. Momijiyama-dōri runs alongside the park, and the section west of the Ōta-machi railway guard has one lane in each direction.

The garden was modelled on the Yatsuhashi Iris Garden in Aichi, a famous site of kakitsubata irises in the old Mikawa Province. Yet no iris plants of any kind now grow in the former garden grounds, so the reference survives only in the layout.
