Tiffany Falls is a 21-metre-high (69 ft) ribbon waterfall located in the Tiffany Falls Conservation Area, just off of Wilson Street East, Ancaster, in Hamilton, Ontario, Canada.

Tiffany Falls was named after Dr. Oliver Tiffany, the district's first doctor. Born in Massachusetts, he studied medicine at the Philadelphia Medical College, and came to Ancaster Township in 1796.

Tiffany Falls Conservation Area is considered a significant natural area. Its bedrock exposures are considered an Earth Science Area of Regional Significance. The central feature of the conservation area is the two waterfalls within it, Tiffany Falls and Washboard Falls, formed by Tiffany Creek.

The area provides a link between the green space corridor along the Niagara Escarpment through the Hamilton urban area, and the extensive natural areas of the Dundas Valley.

The forest area is made up of Eastern Hemlock, Sugar Maple, Red Oak, American Beech, White Ash, Basswood, Black Walnut, Hawthorn, Butternut and White Elm. There are also old field areas and tall shrub thickets.

The highly significant animal, insect, reptile and plant species found within the conservation area include the Purple Clematis, the Hickory Hairstreak butterfly, the Northern Ringneck Snake and the Louisiana Waterthrush.
