Who was the artist of year in country?

The information you are asking for is time-sensitive and may change regularly. However, at the time of my last knowledge update in September 2021, the Country Music Association (CMA) Awards had not yet taken place for the year 2021, so the latest data available at that time was from the 2020 CMA Awards.

Therefore, as of September 2021, the CMA Award for Artist of the Year for the year 2020 went to Eric Church.

Please note that this information could be outdated and there might have been a different artist who won the award in the year 2021. I recommend checking the CMA Awards official website or reputable entertainment news sources for the latest information.
