List of Billboard Hot 100 number-one singles of the 2010s

The Billboard Hot 100 is a chart that ranks the best-performing songs of the United States. Published by Billboard magazine, the data are compiled by Nielsen SoundScan based collectively on each single's weekly physical and digital sales, airplay, and, since 2012, streaming. Streaming became the dominant metric of the Hot 100 beginning in 2015, propelled by technology changes.

A new chart is compiled and officially released to the public every Tuesday in Billboard magazine and on its website. Each chart is dated with the "week-ending" date of the Saturday four days later. (Before 2018, the gap between the chart date and the date of its release was one week longer, and prior to the July 25, 2015 issue, the chart was released every Thursday. )
