What is the Largest Group on deviantART?

As of my last knowledge update, the largest group on deviantART is "The Art of Photography," which focuses on showcasing and promoting photography art. It has amassed a vast number of members and submissions, making it a vibrant community for photographers. However, the platform's dynamic nature may lead to changes in group sizes over time, so it's best to check directly on deviantART for the most current information.
