The Packers Heritage Trail is a self-guided walking and biking heritage trail that traverses locations relating to the history of the Green Bay Packers, an American football team in the National Football League (NFL). All of the 25 sites have bronze commemorative plaques that explain the history of the site and its association to the Green Bay Packers. Each plaque, which has individual sponsors, is either affixed to the side of the relevant building or placed on a pole in front of the site. The Trail is split into three sections: the City Walk, which includes 16 sites and the Packers Heritage Plaza generally in downtown Green Bay; the Packing Plant Spur, which includes 4 sites along Baird Creek; and the Lambeau – Lombardi Spur, which includes another 4 sites along the Fox River.
