Engine No. 1 is an American investment firm. It attracted attention with its campaign to replace four members of ExxonMobil's board of directors despite owning only 0.02% of the company's shares. The firm describes its investment approach as "active ownership", as it prefers to work with management instead of launching activist campaigns.

The fund was founded in December 2020 and its most recent 13F filing indicated that it had $430 million in assets under management. Christopher James is the founder and chief investment officer of the firm and Erik Belz serves as President and chief operating officer. As of October 2021, the fund employed 39 staff.
