List of UK Country Albums Chart number ones of 2021

These are the Official Charts Company's UK Country Albums Chart number ones of 2021. The chart week runs from Friday to Thursday with the chart-date given as the following Thursday. Chart positions are based the multi-metric consumption of country music in the United Kingdom, blending traditional album sales, track equivalent albums, and streaming equivalent albums. The chart contains 20 positions.

In the iteration of the chart dated 1 January, Starting Over by Chris Stapleton spent its sixth week at number one, and would remain there for a seventh week before being displaced by Morgan Wallen's Dangerous: The Double Album, which went on to hold the top spot for six consecutive weeks throughout January and February. Following this, Florida Georgia Line earned their first UK Country chart topper with Life Rolls On, the duo's final album before officially disbanding in 2022. Starting Over would then return to the chart peak in March for an eight and, to date, final week. Steve Earle achieved his eleventh number one album with J.T., a tribute to Earle's son Justin, who died in 2020. Taylor Swift released Fearless (Taylor's Version), her highly anticipated re-recording of her second album Fearless, on 9 April and it immediately debuted atop the chart, remaining there for five consecutive weeks. The album would continue to return to number one throughout 2021, spending a total of sixteen weeks at the peak, the most of any other album released this year. On the chart dated 4 June, Blackberry Smoke's You Hear Georgia debuted and spent the next five weeks at the peak before being replaced by Lady A's What a Song Can Do (Chapter One) EP, with the full album also reaching the top spot for two weeks following its release in October. British group The Wandering Hearts spent four weeks at number one with their self-titled release, while Kacey Musgraves' Star-Crossed became her fourth consecutive number one album on the chart. The only other artists to spend multiple weeks in the top spot were Alan Jackson with his twenty-first album Where Have You Gone, and Bobbie Gentry via the release of a compilation album of the reclusive singer's more jazz-oriented recordings titled The Windows of the World. The final number one of the year was Swift's Fearless (Taylor's Version).
