St. Louis Development Corporation (SLDC) is an umbrella, not-for-profit corporation organized under Chapter 355 of the Missouri State Code with the mission of fostering economic development and growth in the City through increased job and business opportunities and expansion of the City's tax base.

SLDC is directed by its own Board of Directors, and its employees serve as staff support for the City's seven economic development authorities:

Industrial Development Authority (IDA)
Land Clearance for Redevelopment Authority (LCRA)
Land Reutilization Authority (LRA)
Local Development Company (LDC)
Planned Industrial Expansion Authority (PIEA)
Port Authority
Tax Increment Financing Commission (TIF)

The Executive Director of SLDC is also Executive Director for each authority. The agency's department directors make policy recommendations to the authorities, the Mayor, Board of Aldermen, and the business community.

SLDC also administers the Missouri Enterprise Zone Commission in the City through the LCRA, whose members double as the City's Enterprise Zone Commission.

The agency began in July 1988 as the Economic Development Corporation (EDC). In a consolidation to improve efficiency of operations, EDC was renamed SLDC in August 1990.
