Caswell Hill is a district in the city of Saskatoon, Saskatchewan, Canada. It derives its name from an early homesteader Robert Caswell one of the Temperance Colonists of 1883. It is an area of beautiful character homes first built ca. 1905, tiny war-time houses, and newer houses. Caswell is a thriving and diverse community nestled between two economic areas, the downtown core, and the stores lining 33rd Street West.

Caswell Hill is bounded by 22nd Street to the south, H Avenue to the west, 33rd Street to the north, and Idylwyld Drive to the east.^[2]

Streets are laid out east and west, avenues are laid out running north and south. Streets increment in number as travel heads northward. Avenues increment alphabetically as travel proceeds west. The whole of the Caswell Hill community is also laid out in a grid pattern.^[3]

Saskatoon Railway Station (Canadian Pacific) is one of many Saskatoon buildings listed in the Canadian Register of Historic Places. It is a Château style station which was built in 1907. Its current address is 305 Idylwyld Drive North, Idylwyld Drive used to be called Avenue A.^[4]

• Ashworth – Holmes Park (12.68 acres) derived its name from John H. Holmes and John Ashworth. These realtors of the early 1900s purchased most of the land now named the Caswell Hill Subdivision. (Their purchase was bordered by Idylwyld to Avenue H and 22nd to 29th Streets) They subdivided the land and sold it, but donated 10 acres (40,000 m²) to the City which became this park area. [This isn't actually possible, because the Ashworth-Holmes park lies outside of the bounds mentioned above. It is bound by 30th and 31st Streets.]

• Mayfair Swimming Pool – 1025 Ave F North – pool with mini waterslide

Caswell Community Association provides leisure activities for various age groups and operates out of Caswell School^[13]
