Many refer to Boston as "Titletown" because of the massive number of championship teams from the Boston metropolitan area over the years.
The Boston Celtics strengthened the area's claim to the title when they defeated the Dallas Mavericks for their record 18th NBA championship in 2024.
Los Angeles then flipped the script by adding a few more titles, after the Los Angeles Dodgers won the World Series and the LA Galaxy won the MLS Cup. In 2025, the Dodgers added even more championship hardware, after defeating the Toronto Blue Jays to secure their ninth World Series victory.
New York/New Jersey added to their total in 2026 after the New York Knicks won their 3rd NBA Championship in franchise history.
