"Dear Theodosia" is the twenty-second song from Act 1 of the musical Hamilton, based on the life of Alexander Hamilton, which premiered on Broadway in 2015. Lin-Manuel Miranda wrote both the music and lyrics to the song. The song is sung by the character Aaron Burr, originally performed by Leslie Odom Jr.

"Dear Theodosia" also appears twice on The Hamilton Mixtape, first sung by Regina Spektor (featuring Ben Folds), and a reprise version sung by Chance the Rapper and Francis and the Lights.

The song is sung by Aaron Burr and Alexander Hamilton. They welcome their respective children, Theodosia and Philip, into the world. They vow to give their children a better childhood than their own. The Hollywood Reporter acknowledges the coincidence reflected within song, in which "two orphaned men...contemplate the rewards of fatherhood."Vibe added that this "fatherly ballad...gives the dads a chance to reflect on their childhoods whilst contemplating how to be better with their own kids".

The "parenthood song" has a lyrical reference to "blow us all away", in the metaphorical sense of overwhelmingly impressing their parents by their future successes. However, The Huffington Post notes that this lyrical motif will reappear later on in the musical in a more literal context when young Phillip is literally blown away by a gun in a duel.

The Huffington Post wrote that "If John Legend covered this heartbreaker, I'm sure it would hit top ten."The Hollywood Reporter deemed it a "heartbreaker". Yahoo.com declared this the "track of the day" for January 3, 2016, due to a recommendation by a reader who said "I love the way this song tenderly expresses the humbling experience of parenthood shared by two men—both quite roughened to the ways of the world and otherwise vehemently opposed. The common ground of our humanity. ".
