Collaborate, innovate, and transform in Atlanta
ACS Spring 2026 will be taking place in Atlanta. Atlanta is a major economic hub in the southeastern US, known as “The City in a Forest” for its greenery, a significant film and television production center (“the new Hollywood”), and a city rich in civil rights history. The city is home to landmarks like the Martin Luther King Jr. National Historical Park, world-class attractions such as the Georgia Aquarium and World of Coca-Cola, and major corporations like Coca-Cola and Home Depot, all connected by the world’s busiest airport.
Whether in person or online, ACS Spring 2026 will be a meeting for all to explore, engage, and connect. It will be an attendee-centric meeting featuring selected speakers, poster presenters, and exhibitors who are looking forward to sharing their knowledge and making lasting connections.
March 22–26 will be a unique opportunity for the delivery of science. Members of the chemistry enterprise will participate in forward-looking research exchanges and presentations, connect with one another in a range of networking opportunities, and receive information on innovative tools and services to advance the value of chemistry in everyday life.
The meeting will be offered in person and virtual programming via our Digital Meeting Program, with both options ensuring quality engagement for all attendees. Whether participating in person in Atlanta or participating from a home office in the US or another country, ACS Spring 2026 will be an engaging meeting experience for its participants.
ACS Spring 2026 will be a distinctive educational opportunity. It is designed to be a value-added experience that will:
- deliver topical, forward-looking science to its attendees.
- provide diverse networking engagements.
- connect participants looking for career prospects with employment decision-makers.
- serve as a platform for attendees to learn about innovative scientific services, products, and technologies, and to interact with their designers and suppliers.
- offer opportunities for ACS to honor its many volunteers who have helped to elevate the importance of chemistry in our daily lives.
A pillar of the meeting will be interaction. Attendees and presenters will include representatives of the full range of the chemistry community. Content will be shared and received by seasoned professionals who have established themselves in the field, students who are continuing to learn about the many disciplines of the chemistry profession, and everyone in between.
