Johnny Mathis' All-Time Greatest Hits is a compilation album by American pop singer Johnny Mathis that was released in the spring of 1972 by Columbia Records and, despite its title, overlooks a good number of his Top 40 hits ("No Love (But Your Love)", "Teacher, Teacher", "Call Me", "Someone", "Starbright", "Every Step of the Way") in favor of his singles that didn’t make the Billboard Hot 100 ("Venus", "Misty Roses", "If We Only Have Love") and album tracks that weren’t released as singles ("When Sunny Gets Blue", "(Where Do I Begin) Love Story", "My Funny Valentine").

This collection made its first appearance on Billboard magazine's Top LP's & Tapes chart in the issue dated June 24, 1972, and remained there for 15 weeks, peaking at number 141. It received Gold certification from the Recording Industry Association of America on July 9, 1976, and Platinum certification was awarded on November 21, 1986.

Billboard described the compilation as "a collector's must!"
