Stranger to Stranger is the thirteenth solo studio album by American folk rock singer-songwriter Paul Simon. Produced by Paul Simon and Roy Halee, it was released on June 3, 2016 through Concord Records. Simon wrote the material over a period of several years, perfecting it and rewriting it to his liking. Its music is experimental, making use of custom-made instruments by composer and music theorist Harry Partch. Three of the songs on the album are collaborations with Italian electronic artist Clap! Clap!.

His first release in over five years,Stranger to Stranger received wide critical acclaim. It represented Simon's highest-ever debut on the Billboard 200, at number three, and reached number one on the UK Albums Chart.

Simon began writing new material shortly after releasing his twelfth studio album, So Beautiful or So What, in April 2011. Simon collaborates with the Italian electronic dance music artist Clap! Clap! on three songs—"The Werewolf", "Street Angel", and "Wristband". Simon was introduced to him by his son, Adrian, who was a fan of his work. The two met up in July 2011 when Simon was touring behind So Beautiful or So What in Milan, Italy. He and Clap! Clap! worked together via email over the course of making the album. Simon also worked with longtime friend Roy Halee, who is listed as co-producer on the album. Halee, who had retired years earlier, was mostly recruited to advise on how to create natural echo. He was unfamiliar with Pro Tools, so Simon helped him with it. "I always liked working with him more than anyone else," Simon noted.

Andy Greene of Rolling Stone dubbed Stranger to Stranger an "experimental album heavy on echo and rhythm that fuses electronic beats with African woodwind instruments, Peruvian drums, a gospel music quartet, horns and synthesizers." The album makes usage of custom-made instruments, such as the Cloud-Chamber Bowls and the Chromelodeon, which were created by music theorist Harry Partch in the mid-twentieth century. Simon briefly moved the sessions to Montclair State University, where the instruments are stored, in 2013 in order to employ them on the album. "Parch said there were 43 tones to an octave and not 12," Simon remarked in Rolling Stone. "He had a totally different approach to what music is and had to build his own instruments so he could compose on a microtonal scale. That microtonal thinking pervades this album."
