Kidston Island Lighthouse, Coastal lighthouse in Baddeck, Canada.

Kidston Island Lighthouse is a square white wooden tower with sloping walls, standing 14.5 meters (about 48 feet) tall on Kidston Island at the entrance to Baddeck Harbour. It has no keeper's dwelling; the keeper originally lived in the village and reached the light by boat. The present tower, built in 1959, copies the 1911 tower it replaced.

A first lighthouse, a 9-metre square white wooden tower, was lit on Kidston Island on 8 November 1875 at a cost of $1,474.63, with no keeper's dwelling; the keeper was expected to row over from Baddeck. A fourth-order Fresnel lens replaced its three-lamp apparatus in 1909, and a taller 14.5-metre tower with sloping walls followed in 1911. The present tower, an architectural copy, was built in 1959 and automated in 1960.

The lighthouse stands near the former home of Alexander Graham Bell, reflecting the area's connection to innovation and maritime life.

The island is only reachable by boat, and a local service operates during summer months to bring visitors out. Plan your visit when the boat service is running for the best access to the lighthouse.

The first tower, a 9-metre square wooden structure, went into service on 8 November 1875 and cost $1,474.63 to build. No keeper's house was provided: the keeper was expected to live in Baddeck and row out to the island. A three-lamp apparatus lit it until a fourth-order Fresnel lens replaced it in 1909.
