Sedona is a city located in the northern Verde Valley region of Arizona, United States. It straddles the county line between Coconino and Yavapai counties and lies within the Coconino National Forest. The city occupies an area of 19.2 square miles, with only a small fraction being water. Its geography is defined by interior chaparral, semi-desert grassland, and Great Basin conifer woodland biomes, situated amidst notable red rock formations.

Anglo-American settlement began in 1876 when John J. Thompson moved to Oak Creek Canyon. The Sedona post office was established in 1902 with 55 residents, and the area remained unincorporated until later development. Named after Sedona Schnebly, whose husband Theodore Carlton Schnebly was the first postmaster, the community grew as a tourist destination and retirement center starting in the 1950s. Most current infrastructure was constructed during the 1980s and 1990s.

The city is renowned for its array of pink sandstone formations from the Schnebly Hill Formation, which glow under sunlight. Key landmarks include Bell Rock, Cathedral Rock, and the Chapel of the Holy Cross, which rises 70 feet out of a cliff. The landscape features Seven Sacred Pools, Capitol Butte, and Wilson Mountain. The area is bisected by Oak Creek Canyon, providing a scenic backdrop for hiking and mountain biking trails.

Sedona hosts numerous arts organizations and annual events, including the Sedona International Film Festival, established in 1995, and the Sedona Marathon. The town has a vibrant arts community with nearly 100 galleries and festivals such as the Red Dirt Concerts and Hummingbird Festival. It also served as a location for over sixty Hollywood productions from the early film years into the 1970s, including Johnny Guitar and Broken Arrow.

As of the 2020 census, Sedona had a population of 9,684. The climate is cold semi-arid with mild winters and warm summers, averaging just over 17 inches of annual precipitation. Access is primarily via Arizona State Route 89A, located about 120 miles north of Phoenix. The city has limited public transit, making vehicles necessary for accessing trailheads and destinations across its sprawling districts.
