"Sunday Best" is a song by American electro-pop duo Surfaces, consisting of Forrest Frank and Colin Padalecki.

The song was released by TenThousand Projects and Caroline Records on January 8, 2019, as the third single from the duo's second studio album, Where the Light Is.

The song's music video was released on July 11, 2019, and features the duo turning a boring office into a party place.

After the discovery that every day on the calendar is Sunday, a dull office is livened up by the entrance of Forrest and Colin, who introduce an extravagant, brightly colored Hawaiian theme to the room featuring a barbecue, cool drinks, and an inflatable flamingo floatie, beginning a dance party amongst the office staff.

"[5] Surfaces made their late-night television debut when they performed the song on Late Night with Seth Meyers on March 2, 2020.
