Walter W. Winans (April 5, 1852 – August 12, 1920) was an American marksman, horse breeder, sculptor, and painter who participated in the 1908 and 1912 Summer Olympics.

[1] He won two medals for shooting: a gold in 1908 and a silver in 1912, as well as demonstrating the sport of pistol dueling in the 1908 Games.

[3] He was born to Americans William Louis Winans and Maria Ann de la Rue on April 5, 1852, at the Nikolaevsky Railway Works at St. Petersburg, Russian Empire.

In 1884 he prosecuted a Scotsman, Murdoch Macrae, for grazing a lamb on land owned by Winans.

The failure of Winans' prosecution established the right to roam, which was a key element in opening British parklands to the public.
