What was Beyoncé’s first number-one single as a solo artist in the United States?

Beyoncé’s first U.S. number-one solo single was “Crazy in Love.”

Released in 2003 as the lead single from Dangerously in Love, the song features rapper Jay-Z and was produced by Rich Harrison and Beyoncé. Its signature brass hook uses a sample from the Chi-Lites song “Are You My Woman (Tell Me So),” giving the track its instantly recognizable opening.

“Crazy in Love” reached number one on the Billboard Hot 100 and topped charts in several other countries. Its music video, directed by Jake Nava, presents Beyoncé with energetic choreography and helped define the visual identity of her early solo career.

The song won two Grammy Awards at the 46th ceremony in 2004: Best R&B Song and Best Rap/Sung Collaboration. “Baby Boy” also reached number one later in the same album cycle, but it was not Beyoncé’s first solo chart-topper. That distinction belongs to “Crazy in Love.”
