Kyle Ranch, Historic ranch and National Register site in North Las Vegas, Nevada, United States.

Kyle Ranch, also called Kiel Ranch, lies in North Las Vegas, where the city keeps its remnants as Kiel Ranch Historic Park. The 7-acre site holds an adobe building that may date from the Mormon period, the wooden Doll House, a cemetery, and an artesian well with a small wetlands. A 26-acre portion was listed on the National Register of Historic Places in 1975.

Conrad Kiel founded the ranch in 1875 on a 240-acre homestead around a natural spring, where he grew citrus, apples and vegetables. In 1903 part of the land was sold to William A. Clark for the San Pedro, Los Angeles and Salt Lake Railroad. From 1939 to 1958 Edwin and Bette Losee ran the Boulderado Guest Ranch here, and in 1975 a 26-acre portion was listed on the National Register of Historic Places.

The ranch's name comes from Conrad Kiel, though the site is now called Kyle Ranch. From 1939 to 1958 Edwin and Bette Losee ran it as the Boulderado Guest Ranch, a residence for people waiting out Nevada's liberal divorce laws. Earlier, in 1924–39, owner Edwin Taylor's cowboy ranch hands competed in national rodeos.

The site is open to the public as a park with clearly marked pathways, allowing visitors to walk through and view the various buildings and features at their own pace. The location within the city makes it easy to access, and the open grounds are best enjoyed during cooler months when temperatures are more comfortable for exploring.

The cemetery once lay at Carey Avenue and Commerce Street, outside the land sold to the city in the 1970s. UNLV anthropologists exhumed five bodies in 1975 at the city's request; they stayed at the university nearly 45 years before reburial in the park in December 2019. A dedication ceremony followed on Veterans Day, November 11, 2022.
