"Someday Baby" is a Grammy Award-winning song by Bob Dylan and the fifth track on his thirty-second studio album Modern Times, recorded in February 2006.

The song peaked at #98 in Billboard's Pop 100 singles chart, and was featured in a prominent iPod + iTunes commercial that appeared around the time Modern Times was released in early September 2006.

The song is based on "Trouble No More," a folk/blues song written by Muddy Waters and popularized by the Allman Brothers Band, which was in turn based on "Someday Baby Blues" by Sleepy John Estes and popularized by Big Maceo as "Worried Life Blues."

An alternate version of the song, from the same recording sessions, featuring a slower tempo and different arrangement and lyrics, appeared on the 2008 Dylan compilation The Bootleg Series Vol. 8 – Tell Tale Signs: Rare and Unreleased 1989–2006. This version of the song was number 37 on Rolling Stone's list of the 100 Best Songs of 2008.

An edited version of the album track was released on promo CDs.
