The St. Louis Philanthropic Organization (SLPO) is a Missouri nonprofit corporation established in 1984, funded by the proceeds from a settlement with cable television companies. Governed by a volunteer Board of Directors, SLPO has distributed over $9,500,000 in grants and capacity-building support. The organization primarily provides funding through its annual Responsive Grants cycle, which awards up to $10,000 to nonprofits that improve the quality of life for St. Louis City residents. In 2024, SLPO awarded 88 grants, totaling $400,000.

In 2020, SLPO's Board of Directors introduced Capacity Building activities, starting with a workshop series designed to enhance organizational capacity and development through training and resources. Additionally, SLPO hosts a capacity building website that offers recordings of all training sessions, along with related materials and other resources relevant to nonprofits. For more information on the Responsive Grants, visit the "What We Fund" and "Applying for a Grant" sections.
