List of Billboard Hot 100 number ones of 1984

Overall, Prince spent the most weeks at number one in 1984, reigning for seven weeks at the top with "When Doves Cry" and "Let's Go Crazy" (with the Revolution).

However, "Like a Virgin" by Madonna had the longest run at number one of any song which rose into the top position during 1984.

That year, 15 acts achieved their first number one song, such as Yes, Culture Club, Van Halen, Kenny Loggins, Phil Collins, Cyndi Lauper, Duran Duran, Prince, Ray Parker Jr., Tina Turner, John Waite, The Revolution, Billy Ocean, Wham!, and Madonna.

Prince was the only act to hit number one more than once that year, with two.

An asterisk (*) by a date indicates an unpublished, "frozen" week, due to the special double issues that Billboard published in print at the end of the year for their year-end charts.
