Long Island Nonprofits
What We Do
LongIslandNonprofits.org is more than a directory — it’s a regional infrastructure project designed to uplift the entire nonprofit sector on Long Island.
We connect local residents to causes they care about, and we support nonprofit organizations with the visibility, tools, and resources they need to grow.
Whether you're a community member looking to give back or a nonprofit leader searching for guidance, we make engagement easier, smarter, and more impactful.
For the Public: We simplify the search for local, trustworthy nonprofits by organizing them by cause, location, and impact area. Visitors can explore organizations, volunteer opportunities, and events — all in one place.
For Nonprofits: We provide free templates, strategy guides, and promotional support to help small-to-mid-sized organizations operate more efficiently and reach more people. We’re building the infrastructure that grassroots organizations rarely have access to — and doing it locally.
For the Region: By making it easier to discover, support, and invest in local nonprofits, we keep resources circulating within Long Island — strengthening communities, advancing equity, and amplifying the incredible work already being done.
