Downtown Long Beach, California, United States is the location for most of the city's major tourist attractions, municipal services and for numerous businesses. There are many hotels and restaurants in the area that serve locals, tourists, and convention visitors.

Downtown Long Beach is bounded by the Los Angeles River to the west, and Ocean Boulevard to the south (south of Ocean is considered the "Downtown Shoreline", a separate area). Alamitos Avenue roughly delimits downtown to the east, although the City's actual downtown zoning extends a few blocks east of Alamitos. Similarly, downtown effectively ends around 7th Street to the north, but the City's downtown zoning carries as far north as Anaheim Street between Pacific Avenue and Long Beach Boulevard, and up to 10th Street east of that.

The greater downtown area includes the neighborhoods of the East Village Arts District, the West End, North Pine, the Civic Center, and the "Downtown Core" or central business and entertainment area.

Outdated office buildings that have reached the end of their competitive life-cycle are finding a new beginning as residential conversions. In 2014 the city's Municipal Code provided for Adaptive Reuse, which is a "construction or remodeling project that reconfigures existing spaces, structures or buildings to accommodate a new use or to accommodate another purpose than what it was originally designed for." The City created the Adaptive Reuse Incentive Program to guide developers through the process. Re-purposing a building avoids demolition, sending the structure to landfills, while preserving the historic value and unique architecture of downtown Long Beach. Examples of buildings converted for reuse include the Verizon office building on 200 W. Ocean Blvd. in Long Beach which is changed into a mixed-use apartment building over retail.

The Long Beach Professional Building, an eight story poured in place concrete Art Deco medical office tower constructed in 1929 and once in danger of being torn down, was most recently renovated in 2018. The historic building is on the List of City of Long Beach Historic Landmarks and the California Office of Historic Preservation. The building was accepted in 2005 into the National Register of Historic Places. The restoration project was conducted by Global Premier Development and KTGY Architecture + Planning. The structure is now called The Regency Palms, an assisted living and memory care facility.
