The March For Our Lives rally was organised by teenagers after the February 14 shooting at Florida's Marjory Stoneman Douglas High School, where 17 students and staff members were killed.
Activists speaking at the rally called on the government to ban the sale of assault weapons and tighten background checks for everyone purchasing firearms.
Emma González, one of the most well-known survivors of the Parkland school shooting, shared a powerful speech and long moment of silence lasting six minutes and 20 seconds - the same length of time it took the gunman, Nikolas Cruz, to commit the massacre.
Kim Kardashian and Kanye West brought their four-year-old daughter, North, to the march. Other celebrities in attendance included Miley Cyrus, Demi Lovato, Paul McCartney, and Jennifer Hudson.
Former US President Barack Obama shared his support on Twitter.
"Michelle and I are so inspired by all the young people who made today's marches happen. Keep at it. You're leading us forward."
US President Donald Trump spent most of the day at his golf club in Florida and has not spoken out about the protest.
