E. V. Day (American, b.1967) is an installation artist and sculptor whose work examines feminism and sexuality and the links between these issues and popular culture. Day is a trained sculptor, who studied at Berkshire School followed by Yale University, where she received her MFA in Sculpture in 1995.

Shortly after graduating from Yale, Day began her Exploding Couture series, with its first installment, Bombshell, presented at the Whitney Biennial in 2000. The success of Bombshell paved the way for Day to exhibit her work on a solo basis. Her first solo exhibition was Transporter, an installation shown at Henry Urbach Architecture in New York in 2000. This was soon followed by a critically acclaimed solo exhibition, G-Force, presented in New York in 2001 at the Whitney Museum of American Art at Phillip Morris. In G-Force, Day suspends hundreds of pairs of thong underwear, hardened with resin from the ceiling, in traditional fighter jet formations. Many more exhibitions followed her earlier showings, with her work appearing at the Carolina Nitsch Contemporary in New York, the Salomon Contemporary in New York, and the Rhona Hoffman Gallery in Chicago.

Day's work often involves the destruction of women's clothing before display. Her Exploding Couture, the series that began her career, consisted of six exploding dresses, all positioned so that the rags remained identifiable as the whole dress. The impression given is that of a taffeta ball gown just a moment after exploding into pieces. Monofilament lines allow Day to suspend individual pieces, some as small as sequins, from the ceiling to provide the exploding effect. The explosion isn't meant to be violent, instead functioning as a celebration in the form of an energy expansion. This sense of energy uncontained continues through Day's work, with the 2011 piece Flamenco Tornado showing that she hasn't abandoned the idea. A flamenco dress is warped into the shape of a tornado descending from the ceiling in this piece, with the energy of the tornado representing the strength of the dancer's feminine control over the dance. Studios and dealers that handle Day's work include the Carolina Nitch Contemporary Art in New York, the Salomon Contemporary in New York, The Hole Gallery in New York, the Country Club Gallery in Cincinnati, the Rhona Hoffman Gallery in Los Angeles, and The G Fine Art Gallery in Washington, D.C.
