List of Billboard Hot 100 number ones of 2019

The Billboard Hot 100 is a chart that ranks the best-performing songs in the United States. Its data, published by Billboard magazine and compiled by Nielsen SoundScan, is based collectively on each song's weekly physical and digital sales, as well as the amount of airplay received on American radio stations and streaming on online digital music outlets.

Ariana Grande topped the chart for nine weeks with "Thank U, Next" and "7 Rings".

"Old Town Road" by Lil Nas X spent nineteen weeks at number one on the Billboard Hot 100, breaking the record for the longest-running number-one song in the chart's history, and ranked as the best-performing single of the year.

During 2019, fifteen singles reached number one on the Hot 100; a sixteenth single, "Thank U, Next" by Ariana Grande, began its run at number one in November 2018. Of those fifteen number-one singles, four were collaborations. In total, eighteen acts topped the chart as either lead or featured artists, with ten—Swae Lee (as a solo artist), Bradley Cooper, Jonas Brothers, Lil Nas X, Billy Ray Cyrus, Billie Eilish, Shawn Mendes, Lizzo, Lewis Capaldi, and Selena Gomez—achieving their first Hot 100 number-one single.

Lil Nas X's "Old Town Road" was the longest-running number-one of the year, leading the chart for nineteen weeks (one for the song's original version, credited solely to Lil Nas X, and eighteen for a remix featuring Billy Ray Cyrus); in doing so, it broke the record as the longest-running number one single in Billboard history - a record previously held by the sixteen-week runs of both "One Sweet Day" by Mariah Carey and Boyz II Men (1995–96), and "Despacito" by Luis Fonsi and Daddy Yankee featuring Justin Bieber (2017). It also topped the Billboard Year-End Hot 100 ranking as the best-performing single of 2019. In December, Mariah Carey's "All I Want for Christmas Is You" hit number one for the first time 25 years after its debut in 1994, breaking the record for longest climb to the top spot of the Hot 100 since release. It became her 19th number-one single, extending her own record for most number ones among soloists on the Hot 100. It was also the first Christmas song to top the Hot 100 since "The Chipmunk Song" by David Seville and the Chipmunks in 1958–59.^[1] Post Malone and Ariana Grande were the only acts to have multiple number-one songs in 2019, with two apiece.

Chart history

With "Bad Guy", Billie Eilish became the first artist born in the 21st century to have a number-one song on the Hot 100 and the youngest since Lorde in 2013 to top the chart.

Lizzo achieved the longest-running number-one solo song by a female rapper with "Truth Hurts", which topped the Hot 100 for seven weeks.

Mariah Carey's "All I Want for Christmas Is You" hit number one for the first time ever 25 years after its release and became her 19th number-one single, extending her own record for most number ones among soloists on the Hot 100.
