The Skylon Tower, in Niagara Falls, Ontario, is an observation tower that overlooks both the American Falls, New York, and the larger Horseshoe Falls, Ontario, from the Canadian side of the Niagara River.

Standing at 160 metres (520 ft) from street level and 236 metres (775 ft) from the bottom of the falls, the tower required approval from both Canadian and United States air transport authorities, due to its proximity to the international boundary. It was the second tower to be built using the slipform method, in which concrete is continually poured into a form moving slowly up the tower. It was built by Pigott Construction of Hamilton, Ontario. The same methods were also used to build the Inco Superstack in Sudbury, and the CN Tower in Toronto.

The tower features three outside mounted "Yellow Bug" elevators. At the time of their construction they were the first such elevators in Canada. They were designed, engineered and maintained by a division of the Otis Elevator Company from Hamilton, Ontario and can carry passengers to the top of the tower in 52 seconds. Unlike conventional elevators that are guided by side rails, the Skylon elevators operate with a guide rail on the backside only. Special equipment is employed to prevent the cables from becoming tangled in the wind or impeded by snow and ice in the winter. A curtain wall on the outside of the tower behind each elevator protects the counterweight and traveling cables from the elements.

The tower has two restaurants at its top, the lower Revolving Dining Room and the upper Summit Suite Buffet. The Revolving Dining Room seats 276 people and revolves once every hour by resting on a circular rail that is propelled by a 3 horsepower (2.2 kW) motor. An observation deck sits at the tower's summit. The base of the tower features a number of gift shops, fast food restaurants and a large amusement arcade. A floor for conventions is also available.
