"Saturday Sun" is a song by Australian singer-songwriter Vance Joy and was released on 1 February 2018 as the fourth single from Joy's second studio album Nation of Two.

Joy explains "I wrote this last year when I was in Malibu.

I guess it’s about meeting someone really great and not wanting to miss the chance of seeing them again.

When I was writing this song, I was travelling from my little AirBnB in Venice Beach to the studio in Malibu and I got to drive my car on this beautiful stretch of coastal highway and I think that drive inspired some of the lyrics.

[5] Brandon John from Tone Deaf said "In keeping with much of his best work, it’s about as hopeful a tune as you could reasonably ask for, dripping with the optimism of a young romantic as Vance proclaims his new love to the sun over bright acoustic and a swelling horn section.
