List of Hot Adult Contemporary number ones of 1985

In 1985, Billboard magazine published a chart ranking the top-performing songs in the United States in the adult contemporary music (AC) market.

[2] It held the spot for a single week in 1985 before being replaced by "All I Need" by the actor Jack Wagner, best known for his role as Frisco Jones on the soap opera General Hospital.

The British singer Phil Collins spent three weeks in the top spot with "One More Night" and the same length of time at number one with "Separate Lives", a duet with the American vocalist Marilyn Martin.

The only act other than Collins with more than one number one in its own right was the family group DeBarge,[5] who topped the chart with both "Rhythm of the Night" and "Who's Holding Donna Now", although Lionel Richie and Stevie Wonder each achieved one solo chart-topper and also reached number one as part of the charity supergroup USA for Africa.

[11][12] Stevie Wonder's "Part-Time Lover" went one better, topping the same three charts[13][14] and also the Hot Dance/Disco Club Play listing in the form of a remix.
