OneRepublic is an American pop rock band from Colorado Springs, Colorado, formed in 2002. The lineup currently consists of Ryan Tedder (lead vocals, piano), Zach Filkins (guitar, viola), Drew Brown (guitar), Brent Kutzle (bass, cello), Eddie Fisher (drums), and Brian Willett (keyboards, percussion, violin).

The band achieved its first commercial success on Myspace as an unsigned act. In late 2002, after OneRepublic played shows throughout the Los Angeles area, several record labels approached the band with interest, but the band signed with Velvet Hammer, an imprint of Columbia Records. They recorded their first album with producer Greg Wells during the summer and fall of 2005 at his studio, Rocket Carousel, in Culver City, California. The album was scheduled for release on June 6, 2006, but the group was dropped by Columbia two months before the release date.

In 2007, OneRepublic released their debut album, Dreaming Out Loud. Its lead single, "Apologize", was remixed by Timbaland, becoming a huge international success, reaching number one in sixteen countries and subsequently earning them a Grammy Award nomination. The second single, "Stop and Stare", mirrored its predecessor's success. The album was later certified Platinum by the Recording Industry Association of America (RIAA). The band's second album, Waking Up (2009), produced the singles "All the Right Moves", "Secrets", "Marchin On", and "Good Life", with the last reaching the top ten of the US Billboard Hot 100.

OneRepublic's third album, Native (2013), became the band's first top ten album on the Billboard 200, as well as their highest-charting, peaking at number four. Its lead single, "If I Lose Myself", peaked within the top ten in several countries, while the album's third single, "Counting Stars", yielded the band's furthest commercial success, peaking within the top-five in Australia, Canada, Germany, Ireland, New Zealand, the US, and the UK. It also peaked at number two on the US Billboard Hot 100, matching "Apologize".

OneRepublic's fourth album, Oh My My (2016), was preceded by the singles "Wherever I Go" and "Kids"; it was recognized as a change in their sound from previous albums, by critics and by the band themselves. In 2017, the band released the singles "No Vacancy", "Truth to Power", "Stranger Things" (with Kygo) and "Rich Love" (with Seeb). Their fifth studio album, Human, was released in 2021. The band has sold approximately over 16 million records worldwide.
