10 Best Museums in Washington, D.C.: Free Treasures and Family Must-Sees

Washington, D.C. is more than politics and monuments—it’s one of the world’s great museum cities. With more than 70 museums in the region, including the Smithsonian’s network of free institutions, you can dive into American history, global art, science, technology, and niche topics without blowing your budget. Many of the best museums cluster along the National Mall, while others sit in nearby neighborhoods that reward slower, deeper exploration.

Below are 10 of the best museums in Washington, D.C., mixing blockbuster institutions with uniquely D.C. favorites.
