HTO Park, Urban beach park in Inner Harbour, Toronto, Canada.

HTO Park is an urban beach on Lake Ontario in Toronto, built on two 1920s concrete quays: HTO Park West on Maple Leaf Quay and HTO Park East on the former Peter Street Slip. Its sandpit holds fixed yellow metal umbrellas and Muskoka chairs; the umbrellas were designed to evoke Georges Seurat's painting A Sunday Afternoon on the Island of La Grande Jatte. HTO Park East also contains Toronto Fire & Marine Station 334 and EMS Station 36.

HTO Park opened in 2007 on two concrete quays filled in the 1920s and completed by 1929. The eastern quay, the former Peter Street Slip, held Maple Leaf Mills Silos until 1983; the western half of Maple Leaf Quay later became a parking lot. The park now occupies both sites.

The name HTO is a pun on H2O, water's chemical formula, with TO standing for Toronto. The fixed yellow metal umbrellas over the sandpit were designed to evoke Georges Seurat's painting A Sunday Afternoon on the Island of La Grande Jatte. The park was the first of two urban beaches Claude Cormier designed in Toronto, followed by nearby Sugar Beach.

The park sits directly on the waterfront with easy access along Queens Quay West. Its open layout allows flexible exploration, and evening lighting makes it usable after sunset for those wanting extended time outdoors.

HTO Park East occupies the old Peter Street Slip, and its neighbour is Toronto Fire & Marine Station 334, built in 2000, with EMS Station 36 in the same low grey-clad building. The station's blue lettering faces the sand and umbrellas, so a working marine emergency base sits at the edge of the beach.
