Dan Owen Dailey (born 1947) is an American artist and educator, known for his glass sculptures. With the support of a team of artists and crafts people, he creates sculptures and functional objects in glass and metal. He has taught at many glass programs and is professor emeritus at the Massachusetts College of Art, where he founded the glass program.

Emerging from the studio glass movement initiated by Harvey Littleton, Dailey's work has branched out from the mainstream by the incorporation of metal into many of the sculptures. Additionally, he has worked with several glass companies, for more than twenty years. Since 1971, Dailey's work has been featured in more than 150 exhibitions and included in over 350 juried or invitational group shows. His work is in the permanent collection of the Chrysler Museum of Art in Norfolk, Virginia, where an exhibition titled "Dan Dailey: Character Sketch" was held in 2020.
