NCI Small Grants Program for Cancer Research (Omnibus) R03

NCI Small Grants Program for Cancer Research (Omnibus) R03 is the National Cancer Institute's small-project mechanism for cancer research. The current vehicle, PAR-25-078, was archived on February 12, 2026, so the entry is between cycles rather than open. It sits under NIH and NCI and is meant for short, self-contained work that does not need large infrastructure. The award ceiling is $50,000 in direct costs per year for up to two years, with no cost-sharing. Eligibility is unusually broad for an NCI opportunity: universities, nonprofits, small businesses, for-profits, state and tribal governments, foreign organizations, faith-based groups, HBCUs, HSIs, TCCUs, and U.S. territories all qualify. The mechanism is a standing omnibus vehicle even though the current version has expired. Best fit is pilot and feasibility work, secondary analysis, method development, or other small cancer projects that can be done with limited resources. Because NCI often reissues the omnibus vehicle, the practical move is to track the successor PAR rather than rely on this archived version. The breadth of the eligibility list makes it one of the more accessible NCI routes for small, tightly scoped projects.

Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.
