# List of Billboard Adult Contemporary number ones of 2023

Adult Contemporary is a chart published by Billboard ranking the top-performing songs in the United States in the adult contemporary music (AC) market, based on weekly airplay data from radio stations compiled by Broadcast Data Systems.
In the issue of Billboard dated January 7, Australian singer Sia reached number one with "Unstoppable"; the song, originally released in 2016, had experienced fresh popularity on social media sites. The song occupied the top spot for the first 11 weeks of the year before being replaced by "Anti-Hero" by Taylor Swift.
Miley Cyrus topped the chart in April with her track "Flowers", which occupied the top spot for 34 consecutive weeks. It was the singer's first AC number one since she topped the chart in 2009 at the age of 16. In December, Cher topped the chart with "DJ Play a Christmas Song", her first AC chart-topper since "If I Could Turn Back Time" in 1989.
With only four songs topping the chart in 2023, it marks the year with the fewest number ones; the previous record was 1996 with five chart-toppers.
