The Oakland County Trails Advisory Council (OTAC) is a self-guiding organization of trail and greenway stakeholders that is sponsored by Oakland County Parks and Recreation. 

Officially formed in 2003, OTAC aims to assist public and private groups in the development of non-motorized trails in their area of interest; to encourage the connection of individually managed trails; and to initiate actions that result in the continued planning, development, and maintenance of a complete, county- and region-wide network of trails. A County Trails Master Plan was completed in 2008.

OTAC consists of members of all major trail groups in Oakland County, as well as representatives from county departments, state agencies and several non-profit organizations.  Quarterly OTAC meetings provide a venue for communities to share information and and experiences on trail and non-motorized infrastructure programs and projects, which can range from local to state-level efforts.
