"U + Ur Hand" is a song by American pop singer Pink. It was lined up as the third single from her fourth studio album I'm Not Dead (2006). It was released on August 28, 2006, and ignited controversy due to its explicit lyrical content and strong language. The song was written by Pink, Max Martin and Dr. Luke, the same trio who wrote Pink's previous hit single "Who Knew" and the song is also co-written by Rami Yacoub. The two songs eventually became Pink's first two singles to receive Platinum certifications from Recording Industry Association of America (RIAA) and the first two among a series of hits by Martin and Dr. Luke that followed, including Pink's first solo number-one hit on the US Billboard Hot 100, "So What".

"U + Ur Hand" is credited for re-energizing Pink's career in the US and sales of I'm Not Dead in the country, as the album re-entered the Billboard 200 with the song's success, after weeks out of the chart. It peaked at number nine on the Billboard Hot 100, becoming Pink's seventh top-ten hit on the chart, and was ranked number 29 on Billboard's year-end chart for 2007. The single performed well internationally, peaking atop the radio charts of the Czech Republic and Hungary and reaching the top 10 in over 10 other countries.
