King's Highway 29, commonly referred to as Highway 29, was a provincially maintained highway in the Canadian province of Ontario. The 52.29-kilometre (32.49 mi) route connected Highway 2 (King Street) in downtown Brockville with Highway 15 (Lombard Street) south of Smiths Falls. Between those larger settlements, it provided access to the communities of Forthton, Addison, Frankville, Toledo and Newbliss.

When Highway 29 was established in 1927, it consisted of two separated halves. One half connected Brockville with Smiths Falls, while the other connected Carleton Place with Arnprior; Highway 15 provided the only provincial highway link between Smiths Falls and Carleton Place, via Perth. The missing link was filled in 1936. The highway was paved in its entirety the following year. In 1983, it was truncated at Smiths Falls, with the northern portion becoming part of Highway 15. The remainder of Highway 29 remained until 1998, when responsibility for maintenance of the route was transferred to the United Counties of Leeds and Grenville. It is now known as Leeds and Grenville County Road 29
