"I Was on a Boat That Day" is a song recorded by American country music band Old Dominion.

"I Was on a Boat That Day" is a summer party anthem with "joyful ad-libs, raucous instrumentation, and [...] classically Old Dominion rhythms and rhymes".

[2] Lead vocalist Matthew Ramsey said the idea started around six or seven years ago, he told KFDI: “We were kicking it around for a long time.

We’d bring it up and shoot it down I don’t know how many times we decided not to write this song.”[3] In a press release, Ramsey mentioned: "When you listen to 'I Was On a Boat That Day' you are hearing us in the full joy of making music together, from the moment I counted the band off we were smiling from beginning to end.

Clips show partygoers dancing and smiling, and the band members performing the song on a boat.
