"Hello Mary Lou" is a song written by U.S. singer Gene Pitney and Cayet Mangiaracina, first recorded by Johnny Duncan in 1960, and later by Ricky Nelson in 1961.
Nelson's version, issued as the B-side of his No. 1 hit "Travelin' Man", (Imperial 5741), reached No. 9 on the Billboard music charts on May 28, 1961. In the United Kingdom, where it was released as an A-side (with Dorsey Burnette's "It's Late" as the B-side), it reached No. 2. It was also a hit in much of Europe, particularly Norway, where it spent 14 weeks at No. 1. In New Zealand, the song reached No. 4.
A 1991 reissue following the song's use in a TV advert gave the song a second chart run, peaking at number 45 in the UK charts.

Piano was by Ray Johnson, who had succeeded Gene Garf as Nelson's regular session pianist in November 1959. other musicians on the record included Joe Osborne on bass and Ritchie Frost on drums.
