Sula is a census-designated place (CDP) in Ravalli County, Montana, United States.

[2] It is named after the community of Sula, which it encompasses, and was established about 2010, prior to that year's census.

[3] The area was originally called Ross's Hole from Alexander Ross, a Hudson's Bay Company fur trader who had traveled through the area in spring 1824.

In 1889, settlers named the post office after Ursula (Sula for short) Thompson, purportedly the first non-Indian child born in Ross's Hole.

It lies along the East Fork of the Bitterroot River at the west end of Ross' Hole, a wide valley surrounded by mountains.
