Lamar's "DAMN" was announced as the recipient of the prestigious award on Monday, a history-making first for a rap artist, as the music award is typically given to classical or jazz works.
The 2017 Pulitzer Prize for music went to "Angel's Bone," an opera by composer Du Yun.
"DAMN" picked up best rap album at the award show. His song "Humble" also picked up best rap performance, best rap song and best music video.
The New York Times and The New Yorker were also awarded prizes for their reporting on Harvey Weinstein that put the #MeToo movement in the national spotlight.
