Fidelity Charitable, also known as the Fidelity Investments Charitable Gift Fund, is an independent 501(c)(3) public charity established in 1991 that operates the nation's largest donor-advised fund program. It is a major funder and a major source of grant funding via donor-advised funds, enabling donors to contribute a wide range of assets, including cash, securities, cryptocurrency, and non-publicly traded assets like private business interests, and receive an immediate tax deduction while recommending grants to IRS-qualified 501(c)(3) public charities over time. The organization's Giving Account simplifies strategic philanthropy, allowing donors to manage their charitable giving flexibly and efficiently. Fidelity Charitable has facilitated over $100 billion in grants to more than 433,000 nonprofits since its inception, with record distributions such as $14.9 billion in 2024, making it the top grantmaker among donor-advised funds in the United States. Various Fidelity companies provide non-discretionary investment management and administrative services, but the charity is governed by an independent Board of Trustees.

The organization emphasizes growing the American tradition of philanthropy by making giving accessible, simple, and effective. It accepts diverse asset types, with notable increases in non-cash contributions like cryptocurrency (e.g., $506 million in 2024). Fidelity Charitable also runs the Catalyst Fund, a separate grantmaking program led by its Board, which has distributed $95 million since 1994 to support various initiatives. Financially robust, it reported net assets of approximately $66.5 billion as of June 30, 2024, with revenues primarily from donor contributions and investment income. While neutral in political leaning, it has been a conduit for funding to organizations involved in controversial areas, such as those linked to the Islamophobia Network.

Governance includes an independent Board of Trustees with national experts, and it maintains transparency through annual reports, IRS Form 990 filings, and audited financial statements. In response to criticism, Fidelity Charitable modified its guidelines in the early 2000s to restrict grants to private foundations and foreign organizations, aiming to align more closely with public charity standards. No major legal actions or regulatory fines are documented, but its role in channeling funds to politically charged recipients has drawn scrutiny from watchdogs.
