Only foundations with at least 20 grants in each of the last three years (and 20 distinct grantees in the latest), a filing from the last 2 years, and first grants averaging at least $1K are ranked; grants to individuals are left out, and recipient names are matched across years, so a renamed grantee can look new.

Questions about foundations in Delaware
What are the largest foundations in Delaware?
By grants reported on their latest 990s, the largest are Shelby Cullom Davis Charitable Fund Inc ($120.2M across 118 grants), The Kendeda Fund ($60.3M) and Longwood Foundation Inc ($40.8M). Together the top 10 account for 23% of the $1.7B given by the 1,719 grantmakers in Delaware that made at least 5 grants. Organizations that reported large giving in fewer grants, usually a single transfer to an affiliated charity, are left out of the ranking.
How big is a typical foundation grant in Delaware?
The typical grant is about $17K (the median of each grantmaker's average grant). Half of these grantmakers gave less than $125K in total in their latest filing year, so many are small foundations that give to a few organizations they already know. The largest funders make many more grants, but also get the most requests.
Are there community foundations in Delaware?
Yes. We found 4 community foundations in Delaware with grant activity. The largest by giving are Delaware Community Foundation Inc, National Community Foundation and Nia Community Foundation. Community foundations pool gifts from many local donors and usually run open grant rounds for nonprofits in their area, which makes them a good first stop for local funding.
How do I find Delaware foundations that accept unsolicited proposals?
Most private foundations don't run an open application. Their 990-PF says whether they only give to preselected charities, and their past grants show who they actually fund. Start with the funders above whose grant counts and typical grant size fit your budget, then check each profile's grant history for organizations like yours before you reach out. Read the grant prospecting guide.
