Marinepia Matsushima Aquarium (マリンピア松島水族館, Marinpia Matsushima Suizokukan; where Marinepia is a combination of Marine 'Marine' and pia 'pier') was a public aquarium in Matsushima, Miyagi. It opened on April 1, 1927, and closed on May 10, 2015, making it the second longest-running aquarium in Japan, after Uozu Aquarium.

Marinepia Matsushima Aquarium was operated by Sendai express which, in 2001, began to consider a renewal of the aquarium due to aging. Following the opening of Oga Aquarium Gao and Aquamarine Fukushima, the number of visitors to the aquarium began to decrease.

In 2009, Sendai City announced plans to relocate the aquarium to Takasago Central Park in Sendai Port. However, in February 2010, Sendai express canceled its investment in the relocation due to the lack of prospects for raising funds. Then, in 2013, six companies, including Yokohama Hakkeijima Sea Paradise, established the Sendai Aquarium Development Co., Ltd. The new company built Sendai Umino-Mori Aquarium in the hinterland of Sendai Port, where the Marinepia Matsushima Aquarium was supposed to move. Sendai express did not invest in the new aquarium, but the new aquarium accepted animals from the Marinepia aquarium.

In 2011, the Tōhoku earthquake and tsunami caused seawater and mud to flood Marinepia Matsushima Aquarium, breaking the circulation pump. This resulted in the loss of about 5% of the aquarium's approximately 4000 animals. The aquarium received new tropical fish and jellyfish from Kamo Aquarium, Osaka Aquarium, and Kagoshima Aquarium.
