FC Mordovia Saransk (Russian: ФК Мордовия Саранск) was a Russian association football club from Saransk, Republic of Mordovia.

In its current state it was formed in 2005, through the merge of Biokhimik-Mordovia and Lisma-Mordovia.

This result meant that with a round to spare the team won promotion to the Russian Premier League for the 2012–13 season for the first time in its history.

At the end of the 2016–17 season they were relegated for the second year in a row, to the third-tier Russian Professional Football League.
