Plop art (or Plonk art) is a pejorative slang term for public art (usually large, abstract, modernist or contemporary sculpture) made for government or corporate plazas, spaces in front of office buildings, skyscraper atriums, parks, and other public venues.
 The term connotes that the work is unattractive or inappropriate to its surroundings - that is, it has been thoughtlessly "plopped" where it lies.
 "Plop art" is a play on the term pop art.
 According to artnet.com, "plop art" was coined by architect James Wines in 1969.
 The derisive term was eagerly taken up both by progressives (like Wines) and by conservatives.
 Progressives were critical of the failure of much public art to take an environmentally-oriented approach to the relationship between public art and architecture.
 Conservatives liked the term because it suggested something ugly, formless, and meaningless, produced without any real skill or care.
 The very word "plop" suggested something falling wetly and heavily in the manner of excrement — extruded, as it were, from the fundament of the art world, and often at public expense.

Established in 1872 in Philadelphia, the Association for Public Art (formerly Fairmount Park Art Association) is the United States' first private, nonprofit public art organization dedicated to integrating public art and urban planning.
 The Association for Public Art (aPA) commissions, preserves, promotes and interprets public art in Philadelphia, and it is largely due to the work of the aPA that Philadelphia has one of the largest public art collections in the country.
 The aPA has acquired and commissioned works by many famous sculptors (including Augustus Saint-Gaudens, Alexander Stirling Calder, Daniel Chester French, Frederic Remington, Paul Manship, and Albert Laessle); supported city planning projects; established an outdoor sculpture conservation program; and sponsored numerous publications, exhibitions, and educational programs.
 The aPA interprets and preserves more than 200 works of art throughout Philadelphia – working closely with the city's Public Art Office, Fairmount Park, and other organizations and agencies responsible for placing and caring for outdoor sculpture in Philadelphia – and maintains an inventory of all of the city's public art.

Kinji Akagawa (born 1940, Tokyo, Japan) is an American sculptor, printmaker, and arts educator best known for sculptural constructions that also serve a practical function.

Deborah Kay Butterfield (born May 7, 1949) is an American sculptor.
 Along with her artist-husband John Buck, she divides her time between a farm in Bozeman, Montana and studio space in Hawaii.

Julie Rotblatt-Amrany (born July 23, 1958) is an American sculptor and painter identified with the resurgence of the figure in modern art.
 Rebelling against the academic bias against figurative art in the 1970s and 1980s, she has brought new vitality to the subject of the human form by integrating into her work recent discoveries in astronomy, physics, and medicine.
 Her pieces often juxtapose polar opposites such as serenity and tension, and are underpinned philosophically by a view of the universe as a process of endless transformation, with no true beginnings or ends.
 She has produced a wide array of public art, honoring figures from veterans to sports and film icons to astronauts, while simultaneously creating more experimental paintings and sculptures that explore her personal vision.
 She is co-founder of the Fine Art Studio of Rotblatt-Amrany in Fort Sheridan, Illinois, a studio that brings to the United States the aims and traditions of the ateliers of Europe, as well as The Julia Foundation, a not-for-profit arts organization.
