Diller Scofidio + Renfro is a New York City based architectural firm founded by Elizabeth Diller and Ricardo Scofidio in 1979. They are particularly well known for their interdisciplinary approach to architecture. Their influence stems as much, if not more, from their contributions to the theory and criticism of architecture as from their built works. These are sometimes in the form of written work, but more often are in the form of installation art, video art or electronic art.

In 2004 Charles Renfro was made a partner and they have since been known as Diller Scofidio + Renfro. Staying active in the academic world, Elizabeth Diller currently teaches at Princeton University, Charles Renfro is a visiting professor at both Columbia University and Rice University, while Ricardo Scofidio has recently been named Professor Emeritus at Cooper Union.
