About Mary K Chapman Foundation
The Mary K Chapman Foundation is a Tulsa-focused funder that concentrates very large, local investments in community infrastructure and youth-serving institutions. Most dollars flow to a small number of repeat grantees—particularly civic organizations, public library initiatives, and Christian youth programs—suggesting place-based philanthropy aimed at strengthening services and facilities in Greater Tulsa. The presence of a very large line-item/grantee indicates one or two transformational gifts dominate their portfolio.

About Mary K Chapman Foundation
A $7,084,191 grant labeled "See Line 3a Attachment" stands out in the Mary K Chapman Foundation’s recent record, alongside another multi-million-dollar line item the following year. Those large entries sit within a portfolio that also includes repeated support for Tulsa institutions such as YMCA of Greater Tulsa and Tulsa Library Trust, showing a mix of transformational funding and sustained local investment. The foundation’s giving reaches civic organizations, schools, health providers, arts groups, and youth-serving nonprofits, but the pattern is especially concentrated around Greater Tulsa. Recent grants also show recurring support for capital, program, and capacity needs rather than only one type of use. In Tulsa, the foundation backed YMCA of Greater Tulsa in both 2024 and 2025, and it gave substantial support to Tulsa Library Trust for education-related work. Another cluster appears around youth development, with grants to Young Life and several other youth-serving organizations. The result is a regional funder with a strong local footprint and a small number of large awards that shape the overall portfolio.
What Mary K Chapman Foundation Funds
Education is a visible thread in the foundation’s recent giving. It gave $737,013 to Tulsa Library Trust for education and $500,000 to the University of Tulsa for education, then added another $491,007 to the university in 2025. In youth development, the foundation funded Young Life with $675,000 in 2024 and $250,000 in 2025, showing repeated support for that organization. Civic and community work also appears in the grant list: Tulsa Community Foundation received $500,000 for civic and community purposes, while Humble Sons Bike Company received the same amount in 2025 for civic and community work. The arts are part of the mix as well, with $600,000 to Gilcrease Museum Management Trust and $200,000 to Tulsa Ballet.
How Mary K Chapman Foundation Gives
Typical awards cluster at a meaningful scale: the 25th percentile is $25,000, the median is $40,000, and the 75th percentile is $106,250. The recent list also shows several much larger grants, including multiple awards at or above $500,000 and two multi-million-dollar line items. Repetition is common: YMCA of Greater Tulsa, Young Life, Bishop Kelley High School, and the University of Tulsa each appear more than once across the recent grants. The foundation is a regular funder, not a DAF, and it does not fund individuals or make program-related investments. It accepts unsolicited applications through its general grantmaking program, while medical research is by invitation only.
