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

It was released on May 21, 2021 as the lead single from their fourth studio album Time, Tequila & Therapy.

"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".

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.”

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.

The tequila was flowing, the laughter was loud, and we knew in that moment we were creating something that would bring people as much joy as it was bringing us."
