Hot Crossover 30 was a weekly record chart published by American magazine Billboard that ranked the 30 top-performing songs on "crossover" radio stations in the United States featuring a combination of Black, dance and pop music. It was first published in the February 28, 1987, issue of Billboard. The chart was renamed Top 40/Dance on September 9, 1989, and last published on December 1, 1990. Unlike the guitar-oriented rock music heard on contemporary hit radio stations at the time, songs that appeared on the Hot Crossover 30 were often typified by their up-tempo nature, featured drum machines and electronic keyboards, and had varied dance, pop, and R&B influences. Club Nouveau's "Lean on Me" was the first of 65 different songs that topped the chart, and Mariah Carey's "Love Takes Time" was the last.
