A glass floor is transparent section of a floor in a building or a boat. Usually made of a reinforced glass, the most common use is as a tourist attraction. Glass bottom boats are popular for allowing a better view into the sea.

The highest above ground level, in the CN Tower in Toronto, can withstand a weight of 600lbs per sq inch. The highest glass floor in a building in Europe is in the Spinnaker Tower in Portsmouth. The highest in Oceania is in the observation deck of Sky Tower in Auckland.

Glass as a flooring material is also in both residential and commercial structures. Special hollow glass blocks known as glass pavers are often used in combination with a steel or aluminum frame.
