Marc Horowitz (born July 19, 1976, Columbus, Ohio) is an American artist who works in a large variety of media including painting, drawing, sculpture, photography, performance and video.

Marc Horowitz is a Los Angeles-based artist working in painting, performance, video, photography, sculpture, and social practice.

He combines traditional drawing and painting styles, commercial photography, and new media to explore entertainment, class, commerce, failure, success, and personal meaning.

In 2003, Horowitz and a longtime collaborator, Jon Brumit, reinvented themselves as the business team of Sliv & Dulet Enterprises and opened an office in downtown San Francisco (at New Langton Arts).

They staffed their company with 30 people (artists) of various backgrounds to help them "develop a summer line of products and services,"[2] which they pitched to local businesses.

Some examples included a fog removal initiative for the Golden Gate Bridge, a full-service office in a tent, and a Swiss Army Cubicle.

He wrote "Dinner w/ Marc" along with his cell number on a dry-erase board featured in a home office shot for the catalog.

During this time he faced eviction from his apartment, hitchhiked across Los Angeles, hosted Thanksgiving Island, married his long-time true love and had several death threats from his downstairs neighbor.
