Anthony Sigwart de Rosenroll (December 4, 1857 – May 8, 1945) was a politician and businessman in the Canadian province of Alberta. Born in Italy to a family of noble Swiss heritage, he spent his early adulthood in Australia and New Zealand before settling in Canada in 1895. He became a prominent resident of Wetaskiwin, and was acclaimed as its representative to the Legislative Assembly of the Northwest Territories in 1898 and 1902. In Alberta's first provincial election, he was elected as a Liberal to the Legislative Assembly of Alberta, where he remained until 1909. He remained active in business until 1940, and died in 1945 of pneumonia. Early life De Rosenroll was born December 4, 1857, in Castellamare, Italy, to Rudolph and Margaret de Rosenroll. He was descended from Swiss nobility on his father's side, though his line had been absent from Switzerland since 1806.

He spent several years working for the governments of Australia and New Zealand in this capacity, before voyaging to the United States to visit his sister. From there he came to Winnipeg in 1895, ultimately becoming one of the first residents of Wetaskiwin in 1896.

De Rosenroll involved himself in many business ventures. The first of these was a ranching enterprise, in which he initially partnered with Scandinavian settler Thomas R. Jevne and later founded the Rosenroll Ranch near Hay Lakes. Other ventures included the Rosenroll Lumber Co. Ltd., Rosenroll Dairy/Wetaskiwin Creamery, a coal mine, and Rosenroll Ltd., which dealt in real estate and insurance. De Rosenroll was a prominent citizen of his young and growing town. In 1896, he was made a Justice of the Peace and a notary public. Wetaskiwin's Rosenroll Street and nearby Rosenroll were named in his honour (though the former was eventually re-designated with a number, and the latter was renamed to Bittern Lake in 1910).
