Jacob Lake is a small unincorporated community on the Kaibab Plateau in Coconino County, Arizona, United States, at the junction of U.S. Route 89A and State Route 67. Named after the Mormon explorer Jacob Hamblin, the town is known as the "Gateway to the Grand Canyon" because it is the starting point of Route 67, the only paved road leading to the North Rim of the Grand Canyon some 44 miles to the south.
