Brickell (/ˈbrɪkəl/ BRIK-əl) is a neighborhood in Miami, Florida, historically referred to as Southside, located directly east of Interstate 95, north of Coconut Grove, and directly south of the Central Business District and the Miami River. A significant part of Greater Downtown Miami, Brickell is known as the financial district of Miami, as well as for the South Florida region.

Brickell was founded in the mid-19th century, growing to become Miami's "Millionaire's Row" in the early 20th century after the construction of lavish mansions along Brickell Avenue by Mary Brickell; both the avenue and neighborhood were named for Mary Brickell and her husband, William Brickell. By the 1970s, office towers, hotels and apartments began replacing the historic mansions. Brickell overtook the city's central business district to the north, as one of the largest financial districts in the United States. With a fast-growing residential population, Brickell is Miami's most dense neighborhood, with a 2024 population of about 40,000.

With rapid urbanization over the decades, very little remains of the original character of Brickell. Brickell was originally platted for mansions and large homes by Mary Brickell, which thus led to the name "Millionaire's Row." With the growth of the city, especially in the 1970s onwards, Brickell's character began to change with the construction of high-rise office towers along Brickell Avenue, and high-rise residential towers in lower Brickell, south of SE 15th Road (Broadway). A commercial boom in the 1980s brought mass construction of office towers to Brickell, and subsequent construction, would further change the neighborhood into the dense, urban, residential and commercial neighborhood it is today. Some of the historic buildings remaining in Brickell can be seen in the photos below. While not a registered historic landmark, Brickell is home to Tobacco Road, which claimed to be Miami's oldest bar, in business since 1912, with a now-demolished building built in 1915.

Brickell lies immediately east of Interstate 95, including Southwest 3rd Avenue, and extends to the Biscayne Bay. Brickell extends north to the Miami River and south to SW 26th Road (the Rickenbacker Causeway). The neighborhood comprises mostly financial and residential buildings north of Broadway (Southwest 15th Road), and mostly residential buildings south of Broadway. Brickell is home to 31,759 year-round residents.

Although Brickell was known as a financial district, in recent years, construction of numerous residential and mixed-use towers has reshaped the neighborhood into a residential community. Brickell now offers residents a walkable lifestyle, where work and entertainment converge. Ongoing development has expanded the dense urban core of Brickell from Brickell Avenue west to Interstate 95, making the Metrorail line and new and expanding Underline Park the center of the neighborhood. As of 2010, 80,000 residents live in Brickell, among them, famous celebrities such as José José, Luis Miguel, Clinton Portis, Jennifer Lopez and Marc Anthony.

Within Brickell is Mary Brickell Village, which was the center of the neighborhood's entertainment district when it opened in 2006. It remains to be a popular gathering spot that includes restaurants, boutique retail shops, and a variety of service providers. The project design was inspired by a mediterranean-style village with open squares that facilitate social gatherings and entertainment events. Its design now contrasts to the steel Manhattan-like skyscrapers that surround it, but offers a welcoming scale more akin to coastal Mediterranean villages in Europe. Plans are in place to redevelop a portion of this space.

To the north of Brickell is Downtown, with most of the area's public elementary schools and Miami Dade College's Wolfson Campus. Downtown is also home to the Miami Main Library, as well as various parks, theatres, museums, and sporting venues. South of Brickell is Coconut Grove, with Mercy Hospital, CocoWalk, Dinner Key, Villa Vizcaya, as well as many historic sites and parks. Coconut Grove also has many of Miami's best private schools, such as Ransom Everglades, Carrollton School of the Sacred Heart, and Immaculata-Lasalle High School.

West of Brickell is Little Havana, extending from Interstate 95 westward. East of Brickell is Biscayne Bay, and eastward along the Rickenbacker Causeway, is Virginia Key and Key Biscayne. Both keys have many public beaches, nature preserves, parks, and various other cultural venues. Also east, along the MacArthur Causeway is South Beach.
