"Endlessly" is a 1959 single by Brook Benton. The follow-up to his breakthrough hit "It's Just a Matter of Time", it reached number 12 on the Billboard Hot 100. Its B-side, "So Close", also reached the chart, peaking at number 38. "Endlessly" also was Benton's first chart success in the UK, where it reached #28.

In 1970, country singer Sonny James, who had topped the country charts with a remake of "It's Just a Matter of Time" earlier in the year, released his version of "Endlessly" as a single. It was James' sixteenth number-one song on the U.S. country singles chart. The single spent three weeks at number one and a total of fourteen weeks on the chart.

British singer Tom Jones also recorded a version, released on his 1965 debut album Along Came Jones.
