Robert Lopez (born February 23, 1975) is an American songwriter for musicals and a playwright, best known for co-creating The Book of Mormon and Avenue Q, and for co-writing the songs featured in the Disney animated films Frozen, its sequel Frozen 2, and Coco, with his wife Kristen Anderson-Lopez. He is signed to Disney Music Publishing.

Lopez is one of only twenty-eight people who have won an Emmy, a Grammy, an Oscar, and a Tony Award, nicknamed by Philip Michael Thomas in 1984 as the "EGOT". He additionally holds the distinction of being the youngest person to win an EGOT. He is also the only person to have won all four awards more than once, having won two Oscars, three Tonys, three Grammys, and four Emmys. With a second set of competitive wins beginning with his June 27, 2010, Emmy and concluding with his March 4, 2018, Academy Award, he broke his own 'fastest to complete' record, establishing a new fastest EGOT interval at 7 years and 8 months. This was later broken by Pasek and Paul (7 years, 7 months).
