YMCA Camp Belknap is an all-boys summer resident camp in Tuftonboro, New Hampshire, on the shores of Lake Winnipesaukee. Founded in 1903, on Winnipesaukee's Timber Island, in the shadow of Belknap Mountain, its likely namesake. Relocated to Tuftonboro in 1907, this boys' camp was owned and operated by the New Hampshire YMCA until the demise of the state Y in 1996. It is now an independent non-profit affiliated with the national Y.
