In 1999, Koons commissioned a song about himself on Momus's album Stars Forever.
A drawing similar to his Tulip Balloons was placed on the front page of the Internet search engine Google. The drawing greeted all who visited Google's main page on April 30, 2008, and May 1, 2008.
In 2006 Koons appeared on Artstar, an unscripted television series set in the New York art world. He had a minor role in the 2008 film Milk playing state assemblyman Art Agnos.

In February 2024, a SpaceX rocket carrying 125 of Koon's stainless steel miniature moon sculptures departed from the Kennedy Space Center in Florida. The sculptures, named after historical figures such as Leonardo da Vinci and Billie Holiday, were part of a larger project involving a lunar lander designed by Intuitive Machines. The lander, which also carried NASA equipment, reached the Moon on February 22. Koons, inspired by President Kennedy's vision of space exploration, saw this project as a way to inspire society. This endeavor, which included plans for larger sculptures on Earth and corresponding NFTs, aimed to be the first authorized artwork on the moon, protected under the Artemis Accords.
Koons acted as curator of an Ed Paschke exhibition at Gagosian Gallery, New York, in 2009. He also curated an exhibition in 2010 of works from the private collection of Greek billionaire Dakis Joannou at the New Museum in New York City. The exhibition, Skin Fruit: Selections from the Dakis Joannou Collection, generated debate concerning cronyism within the art world as Koons is heavily collected by Joannou and had previously designed the exterior of Joannou's yacht Guilty.
Koons was the artist named to design the seventeenth in the series of BMW "Art Cars". His artwork was applied to a race-spec E92 BMW M3, and revealed to the public at The Pompidou Centre in Paris on June 2, 2010.

In 2013, Koons collaborated with American singer-songwriter and performance artist Lady Gaga for her third studio album, ARTPOP. The album cover depicts a nude sculpture of Gaga made by Koons behind a blue ball sculpture, and pieces of other art works in the background such as Birth of Venus painted by Sandro Botticelli, which inspired Gaga's image through the new era, including in her music video for "Applause" and the performance of the song at the 2013 MTV Video Music Awards. The image of the cover was revealed piece-by-piece in a social marketing campaign where her fans had to tweet the Twitter hashtag "#iHeartARTPOP" to unlock it. The song "Applause" itself includes the lyrics "One second I'm a Koons, then suddenly the Koons is me."
In 2005, Koons and fashion designer Stella McCartney recreated his signature Rabbit sculpture as a platinum necklace pendant for her eponymous brand. A 2006 Stella McCartney collection featured prints of Koons's "Lips", "Stream", and "Pink Bow" paintings. Both in 2020 and 2005, Koons worked with Stella McCartney on graphic T-shirts.
In April 2017, Koons collaborated with the French luxury fashion house Louis Vuitton for the "Masters Collection" and designed a series of handbags and backpacks featuring the reproductions of his favorite masterpieces by the Old Masters, such as Leonardo da Vinci, Titian, Vincent van Gogh, Peter Paul Rubens and Jean-Honoré Fragonard. Later that year he presented another handful of bags and accessories featuring the reproductions of works by Claude Monet, J. M. W. Turner, Édouard Manet, Paul Gauguin and François Boucher. The prices range from $585 for a key chain to $4,000 for the large carryall. he also collaborated with singer Cupcakke multiple times in 2019.
Koons has also produced some fine wine-related commissions. In December 2012, Chateau Mouton Rothschild announced that Koons was the artist for their 2010 vintage label – a tradition that was started in 1946. Other artists to design labels include Pablo Picasso, Francis Bacon, Salvador Dalí and Joan Miró, amongst others. In August 2013, Dom Pérignon released their 2004 vintage, with a special edition done by Koons, as well as a made-to-order case called the 'Balloon Venus'.
From February 15 to March 6, 2008, Koons donated a private tour of his studio to the Hereditary Disease Foundation for auction on Charitybuzz. From his limited-edition 2010 Tulip designs for Kiehl's Crème de Corps, a portion of the proceeds went to the Koons Family Institute, an initiative of the International Centre for Missing & Exploited Children. Since his relationship with the International Centre began, Koons has given over US$4.3 million to the Institute.
