Kaladar is a community in the municipality of Addington Highlands in Lennox and Addington County Ontario, Canada. It is located at the junction of Highway 7 and Highway 41.
To the north is Bon Echo Provincial Park. Other nearby natural areas are the Kaladar Pine Barrens Conservation Reserve and Puzzle Lake Provincial Park.
This area was first settled following the construction of the Addington Road in 1857. It was originally named Scouten after its first postmaster. The old CPR rail bed passing through the town has become part of the Trans Canada Trail. The Kaladar fire tower was situated at the north end of the village just off the highway, but was removed some time in the 1970s or 1980s.
