Infinity is the third extended play by American indie pop band AJR, published through Warner Music Group and the band's label AJR Productions. It was released on September 23, 2014, to accommodate the delay of the band's debut studio album, Living Room (2015). The EP produced the sole single "Infinity", which received praise from critics and commercial success. The song would later be included on their debut album alongside "Pitchfork Kids".
