Ann Arbor is a city in the U.S. state of Michigan and the seat of government of Washtenaw County.  Ann Arbor is home to the University of Michigan. Several performing arts groups and facilities are on the University of Michigan's campus, as are museums dedicated to art, archaeology, and natural history and sciences.

Founded in 1879, the University Musical Society is an independent performing arts organization that presents over 60 events each year, bringing international artists in music, dance, and theater. Since 2001 Shakespeare in the Arb has presented one play by Shakespeare each June, in a large park near downtown. Regional and local performing arts groups not associated with the university include the Ann Arbor Civic Theatre, the Arbor Opera Theater, the Ann Arbor Symphony Orchestra, the Ann Arbor Ballet Theater, the Ann Arbor Civic Ballet (established in 1954 as Michigan's first chartered ballet company), The Ark, and Performance Network Theatre. Another unique piece of artistic expression in Ann Arbor is the fairy doors. These small portals are examples of installation art and can be found throughout the downtown area.

The Ann Arbor Hands-On Museum is located in a renovated and expanded historic downtown fire station. Multiple art galleries exist in the city, notably in the downtown area and around the University of Michigan campus. Aside from a large restaurant scene in the Main Street, South State Street, and South University Avenue areas, Ann Arbor ranks first among U.S. cities in the number of booksellers and books sold per capita. The Ann Arbor District Library maintains four branch outlets in addition to its main downtown building. The city is also home to the Gerald R. Ford Presidential Library.

Several annual events—many of them centered on performing and visual arts—draw visitors to Ann Arbor. One such event is the Ann Arbor Art Fairs, a set of four concurrent juried fairs held on downtown streets. Scheduled on Thursday through Sunday of the third week of July, the fairs draw upward of half a million visitors. Another is the Ann Arbor Film Festival, held during the third week of March, which receives more than 2,500 submissions annually from more than 40 countries and serves as one of a handful of Academy Award–qualifying festivals in the United States.

Ann Arbor has a long history of openness to marijuana, given Ann Arbor's decriminalization of cannabis, the large number of medical marijuana dispensaries in the city (one dispensary, called People's Co-op, was directly across the street from Michigan Stadium until zoning forced it to move one mile to the west), the large number of pro-marijuana residents, and the annual Hash Bash: an event that is held on the first Saturday of April. Until (at least) the successful passage of Michigan's medical marijuana law, the event had arguably strayed from its initial intent, although for years, a number of attendees have received serious legal responses due to marijuana use on University of Michigan property, which does not fall under the city's progressive and compassionate ticketing program.

Ann Arbor is a major center for college sports, most notably at the University of Michigan. Several well-known college sports facilities exist in the city, including Michigan Stadium, the largest American football stadium in the world and the third-largest stadium of any kind in the world. Michigan Stadium has a capacity of 107,601, with the final "extra" seat said to be reserved for and in honor of former athletic director and Hall of Fame football coach Fitz Crisler. The stadium was completed in 1927 and cost more than $950,000 to build. The stadium is colloquially known as "The Big House" due to its status as the largest American football stadium. Crisler Center and Yost Ice Arena play host to the school's basketball (both men's and women's) and ice hockey teams, respectively. Concordia University, a member of the NAIA, also fields sports teams.

Ann Arbor is represented in the NPSL by semi-pro soccer team AFC Ann Arbor, a club founded in 2014 who call themselves The Mighty Oak.

A person from Ann Arbor is called an "Ann Arborite", and many long-time residents call themselves "townies". The city itself is often called "A²" ("A-squared") or "A2" ("A two") or "AA", "The Deuce" (mainly by Chicagoans), and "Tree Town". With tongue-in-cheek reference to the city's liberal political leanings, some occasionally refer to Ann Arbor as "The People's Republic of Ann Arbor" or "25 square miles surrounded by reality", the latter phrase being adapted from Wisconsin Governor Lee Dreyfus's description of Madison, Wisconsin. In A Prairie Home Companion broadcast from Ann Arbor, Garrison Keillor described Ann Arbor as "a city where people discuss socialism, but only in the fanciest restaurants." Ann Arbor sometimes appears on citation indexes as an author, instead of a location, often with the academic degree MI, a misunderstanding of the abbreviation for Michigan.
