Top 20 museums in the United States

We take a look at the nation’s most visited art, science & history institutions

Across the United States, countless museums captivate millions of visitors annually with their diverse exhibits, immersive experiences, and cutting-edge programmes. From iconic institutions like the Smithsonian to dynamic science centres and cultural hubs, the top museums in the United States shape how we understand the world.

In this article, we highlight the leading museums in the United States based on the insights from the TEA/AECOM Museum Index 2023. This annual report sheds light on visitor trends, attendance growth, and the evolving role of museums in a post-pandemic world.

Global COVID-19 restrictions finally ended in 2023 as countries lifted the last travel bans and restrictive operating standards. Attendance at the world’s top 25 theme parks grew by 23% compared to 2022 data, and museums saw a 95% increase, having experienced more detrimental effects during the pandemic.

“Museums have really started embracing more interactive and dynamic exhibits as a means to attract audiences and retain interest in their institutional mission,” says Linda Cheu, vice president with AECOM’s Economics + Advisory practice, in the report’s introduction.

“While the digital or virtual footprint of museums dramatically expanded during the peak of the pandemic, we are now seeing the physical spaces being revitalized through reinvestment. The resulting experiences are indicative of a bright future for cultural institutions around the world.”
