The biggest autism organizations in the United States are large, well-established groups that provide a wide range of services, advocacy, support, and resources for individuals with autism and their families. These organizations often operate nationwide, offering everything from early intervention and education to adult services, policy advocacy, and community support. Here are some of the most prominent:
**1. Autism Society of America**
One of the oldest and largest grassroots autism organizations in the country, the Autism Society focuses on improving the lives of all affected by autism through advocacy, education, information and referral, support, and community outreach. They maintain a national directory of autism programs, clinics, and support groups, helping families find local resources. Their work spans from early childhood through adulthood, emphasizing acceptance and inclusion.
**2. Autism Speaks**
Autism Speaks is one of the most widely recognized autism organizations in the US. It funds research, raises awareness, and provides toolkits and resources for families, educators, and healthcare providers. They also advocate for policies that support people with autism and their families. Autism Speaks has a broad reach and offers a variety of programs, including support for diagnosis, early intervention, and transition to adulthood.
**3. National Council on Severe Autism (NCSA)**
This organization focuses specifically on individuals with severe forms of autism and their families. NCSA advocates for recognition, policy changes, and solutions tailored to the unique needs of those with profound autism. They work to improve healthcare access, caregiver support, and quality of life for this often underserved population. Their efforts include pushing for integrated multidisciplinary healthcare and addressing systemic barriers.
**4. Glenwood**
Glenwood is a nonprofit agency providing comprehensive services for children and adults with autism and other behavioral health needs.

Glenwood serves a wide age range, from toddlers to seniors, and tailors programs to individual needs, emphasizing empowerment and community integration.
**5. Autism Family Services of New Jersey (AFSNJ)**
AFSNJ is a regional but influential organization that supports families through programs like after-school care, recreational activities, and large community events such as their Annual Autism Beach Bash. They focus on providing social opportunities and support networks for families, helping to address the challenges of obtaining appropriate services and fostering community connections.
**6. Autism Network International (ANI)**
Founded by autistic adults, ANI offers a unique perspective by emphasizing autistic identity and acceptance. They build community through newsletters, conferences, and online communication, providing families and caregivers with insights directly from autistic individuals. This autistic-led approach helps shift the focus toward strengths and lived experience, enriching understanding and support.
**7. Friends of Children with Special Needs (FCSN)**
Based in California, FCSN runs inclusive programs such as family activities, summer camps, and day programs for individuals with developmental disabilities, including autism. Their programs are often free or low-cost, making them accessible to families regardless of income. They focus on strengthening the entire family unit by offering support groups for parents alongside recreational and educational opportunities for children.
**8. Local Support Networks and Meetup Groups**
Beyond the large national organizations, many families benefit from local autism support groups, libraries hosting sensory-friendly events, and caregiver-led Meetup groups. These grassroots efforts provide informal, community-based support and social opportunities that can be less intimidating than clinical settings. They foster belonging and practical advice exchange among families facing similar challenges.
These organizations collectively cover a broad spectrum of needs—from research and policy advocacy to direct services and community building. They serve children, adults, and families affected by autism, addressing diverse needs including education, healthcare, social inclusion, and caregiver support. Their work is vital in improving quality of life and expanding opportunities for people on the autism spectrum across the United States.
