Square Enix Montréal was a Canadian video game developer based in Montreal. It created the Go series of turn-based puzzle games for mobile devices based on former Eidos Interactive intellectual properties.

Square Enix Montréal was founded in November 2011 as a traditional studio under Square Enix Europe. Initially planning to create a new Hitman series game for consoles and employ several hundred people, its parent company mandated it to produce mobile games in 2013. The company developed prototypes for two mobile Hitman games, which became the board game-inspired puzzle game Hitman Go (2014) and the shooter Hitman: Sniper (2015). The commercial success of the latter and the critical success of the former led to two additional titles in the Go series: Lara Croft Go (2015), based on the Tomb Raider series, and Deus Ex Go (2016), based on the Deus Ex series. It focused on free-to-play games after 2016 and later added the London-based studio Square Enix London Mobile founded in 2021.

Embracer Group acquired Square Enix Montréal alongside several other Square Enix Europe assets in August 2022, which formed CDE Entertainment. The studio was briefly rebranded Onoma in October 2022 before it closed the next month.
