"Waterloo" was a number-one hit for country singer Stonewall Jackson in 1959. It was written by John D. Loudermilk and Marijohn Wilkin. The single was the most successful of Jackson's career, spending five weeks at number one on the U.S. country music chart. The B-side of "Waterloo", "Smoke Along the Track", reached number 24 on the country chart. "Waterloo" was also Jackson's only Top 40 hit, where it stayed on the chart for 16 weeks, peaking at number four on the Billboard Hot 100 pop chart.

The song tells of three famous people who, because of their actions, "met their Waterloo" – Adam (who ate the "apple"), Napoleon (at the namesake battle), and Tom Dooley (who was hanged for murder).
