List of Chad's Chart Number ones of 2021

My Chart is a chart that ranks the best-performing songs in the United States. It is based collectively on each song's weekly streaming from me as well as the amount of airplay received on my local radio stations. Twenty-four songs reached the top spot in 2021, with Ten being debuts. So far Fourteen artists reached the top spot for the first time either as a lead or featured artist, those being, Ofenbach, Quarterhead, Norma Jean Martine, Olivia Rodrigo, Lilypichu, Toosii, Riton, Nightcrawlers, Mufasa and Hypeman, Tate McRae, Troye Sivan, Clairo and Måneskin.
