Cinesite Vancouver (formerly known as Nitrogen Studios Canada, Inc., commonly referred to as Nitrogen Studios) is a Canadian animation company founded by husband and wife duo Greg Tiernan and Nicole Stinn.

On March 7, 2017, Nitrogen was acquired by British visual effects and feature animation studio company Cinesite, becoming their Vancouver operations.

One poster stated that Tiernan had developed a reputation for "disturbing behaviour and abusive management style".
