Irvine Ranch Conservancy is a California non-profit organization.

It was founded in 2005 to help care for the tens of thousands of open space acres preserved in public ownership on the historic Irvine Ranch. The Conservancy works with landowners such as OC Parks, City of Irvine and City of Newport Beach to preserve and restore these lands and help people enjoy them. The Conservancy has an independent board of directors overseeing its strategy and operations.
