The Yinka Dene Language Institute (YDLI) is an organization based in Stoney Creek, British Columbia, whose purpose is the study and maintenance of the language and culture of Dakelh and other First Nations people in northern British Columbia.

It was founded in 1988 by the Carrier Sekani Tribal Council, the College of New Caledonia, School District 55 Burns Lake, School District 56 Nechako and School District 28 Quesnel.^[1] The late Mary John, Sr. was one of the founders of YDLI and was Permanent Honorary Chair until her death in 2004.
