Some credit a story told of Captain B.L.E. Bonneville of the U.S. Army as the source of the name. After trekking for weeks through dry and rough terrain, his exploration party reached an overlook with a view of the Boise River Valley. The place where they stood is called Bonneville Point, and is located on the Oregon Trail east of the city. According to the story, a French-speaking guide, overwhelmed by the sight of the verdant river, yelled "Les bois! Les bois!" giving the area the name.
But the name "Boise" may actually derive from earlier mountain man usage, which contributed their naming of the river that flows through it. In the 1820s, French Canadian fur trappers set trap lines in the vicinity where Boise now lies. In a high desert area, the tree-lined valley of the Boise River became a prominent landmark. They called this "La rivière boisée", which means "the wooded river."
The original Fort Boise was 40 miles (64 km) west, down the Boise River, near the confluence with the Snake River at the Oregon border. This fort was erected by the Hudson's Bay Company in the 1830s. It was abandoned in the 1850s, but massacres along the Oregon Trail prompted the U.S. Army to re-establish a fort in the area in 1863, during the U.S. Civil War. The new location was selected because it was near the intersection of the Oregon Trail and a major road connecting the Boise Basin (Idaho City) and the Owyhee mining areas. Both areas were booming at the time. Idaho City was the largest city in the area, and as a staging area to Idaho City, Fort Boise grew rapidly. Boise was incorporated as a city in 1864. The first capital of the Idaho Territory was Lewiston, but Boise replaced it in 1865.

The name Boise comes from the French word boisé, which means "wooded". Many people assume that it means "tree", but the French word for "tree" is arbre, whereas the word bois means "wood". One legend claims that French-Canadian fur trappers of the early 1800s came over the mountains looked down upon the Boise River Valley and exclaimed "Les bois!" (the wood!), and that this is also how Boise gained its nickname 'The City of Trees'. In actuality, the name was apparently a translation of an earlier English name for the Boise River, the Wood River. Wood River was traditionally called Pine River, but was changed in 1867.
