List of Billboard number-one country songs of 2020
and Country Airplay are the two main charts that rank the top-performing country music songs in the United States, published by Billboard magazine. Hot Country Songs ranks songs based on digital downloads, streaming, and airplay not only from country stations but from stations of all formats, a methodology introduced in 2012. Country Airplay, which began being published in 2012, is based solely on country radio airplay, a methodology that had previously been used from 1990 to 2012 for Hot Country Songs.
Both charts began the year with songs at number one that started their runs in 2019; "10,000 Hours" by Dan + Shay and Justin Bieber holding the top spot on the Hot Country Songs chart, and "Even Though I'm Leaving" by Luke Combs atop the Country Airplay chart. Having spent the last 11 weeks of 2019 at number one on Hot Country Songs, "10,000 Hours" spent its 15th consecutive week in the top spot in the issue of Billboard dated January 25, and in the same week topped the Country Airplay listing for the first time. It remained at number one on Hot Country Songs until March 14, when it was dethroned by "The Bones" by Maren Morris. Having reached number one in its 53rd chart week, the song logged the second-slowest climb to the top. In addition, it was the first number one on the chart for Morris and made her the first solo female artist to top the chart since Kelsea Ballerini with "Peter Pan" in the fall of 2016. In May 2020, it charted its 11th week at number one on Hot Country Songs, surpassing Taylor Swift's "We Are Never Ever Getting Back Together" as the longest-lasting number one by a solo female on that chart. When Jimmie Allen's "Make Me Want To" reached number one in its 58th chart week on the Country Airplay chart dated March 7, it set two records: the slowest climb to number one in that chart's history, as well as the longest chart run. In June, Travis Denning broke this record with "After a Few", which reached the top in its 65th week.
