The 91st Scripps National Spelling Bee was held at the Gaylord National Resort & Convention Center in National Harbor, Maryland (its eighth year at this location) from May 29 to 31, 2018. The winner was 14-year-old Karthik Nemmani, an eighth grader from McKinney, Texas, who correctly spelled "koinonia" for the win. Due to a rule change in how spellers can make it to the Bee, the bee's total field of 515 spellers was a large increase over prior years.
