Dude ranches near Yellowstone, by which gate you use
Many ranches say they are near Yellowstone. The park has five entrances, hours apart, so what matters is which gate your ranch is closest to.
Why the gate matters more than the mileage
Yellowstone is bigger than Rhode Island and Delaware together, with five entrances spread around its edge. Two ranches can both sit 40 miles from the park and be a five-hour drive apart, because getting between gates means going around the outside.
So this list is sorted by entrance rather than by distance. The entrance decides what you can see in a day trip and how long you spend in the car.
North gate: Paradise Valley and the Gallatin
The north entrance at Gardiner is the only one open to cars all year. Mountain Sky sits about 23 map miles from it in Paradise Valley, the shortest run of any ranch here. Lone Mountain is about 31 at Big Sky, and Nine Quarter Circle, Elkhorn Ranch and Covered Wagon are all about 46 up the Gallatin.
This is also the Bozeman side, so it is the easiest group to fly to. Lone Mountain is about 40 minutes from the airport, and Elkhorn runs paid transfers from it.

West gate: West Yellowstone
The west entrance sits at the town of West Yellowstone, Montana. Parade Rest, on Grayling Creek north of town, puts itself 10 miles from it by its own count, and its packages include fly-fishing lessons and gear.

South gate: Jackson Hole and Dubois
The south entrance runs straight out of Grand Teton National Park, so these ranches give you two parks from one base. Lost Creek, Triangle X and Moose Head are all about 33 map miles out at Moose, and Red Rock and Goosewing about 36 at Kelly. Triangle X is inside Grand Teton National Park itself, and Moose Head is surrounded by it.
Spotted Horse, 16 miles south of Jackson on the Hoback, and Darwin, far up the Gros Ventre, use the same gate but start from the Jackson side.
Over Togwotee Pass, the five Dubois ranches sit about 66 miles from the same gate. Bitterroot, CM Ranch, Lazy L&B, Triangle C and Absaroka are a longer drive but a quieter valley, and Lazy L&B sits at 7,200 feet.

Northeast gate: the Beartooth side
The Cooke City entrance is the quiet one, reached over the Beartooth Highway, which closes with the snow. The ranches on this side are mostly working outfits rather than park bases. Paintbrush Adventures is about 42 map miles out at Absarokee, Lonesome Spur about 53 at Bridger, and Sweet Grass about 56 at Big Timber. Dryhead is about 83, down in the canyon country.
If you came for cattle rather than geysers, this is the side to look at: three of those four put guests in real ranch work.

East gate: the North Fork out of Cody
The east entrance is at the top of the North Fork of the Shoshone, a road that climbs from Cody through Shoshone National Forest. Two ranches on this side give their own distance to the gate: Blackwater Creek 15 miles and UXU a 17-mile drive. Crossed Sabres, also west of Cody, gives none. Blackwater's six-night weeks include a guided day in the park.
Cody's airport is about 45 minutes from Blackwater Creek, and its six-night guests are collected for free.

Plan your park day with the ranch
A ranch week is a full schedule. Most of these ranches ride mornings and afternoons, and the ones that run a park trip treat it as an off-ranch outing on a set day, not something you do whenever you like. Sweet Grass, for instance, lists Yellowstone day trips as a separate extra rather than part of the week.
If seeing the park is the point of the trip, say so when you book and ask which day it happens. If riding is the point, the park is a bonus and the gate matters less than it looks.

One last thing
The mileages here are straight-line distances from the ranch's nearest listed town to the gate, measured off the map. Mountain roads are longer than that, sometimes much longer, and passes close in winter. Most ranch pages here list the nearest airport and whether the ranch collects you, which matters more for your travel day than the mileage.
