J to tha L–O! The Remixes is a remix album by American singer Jennifer Lopez, released February 1, 2002 by Epic Records. It contains remixes from Lopez's first two studio albums: On the 6 (1999) and J.Lo (2001). It features artists including P. Diddy, Ja Rule, Fat Joe and Nas, and includes dance and hip hop remixes of past singles. It was Lopez's second album to feature a Parental Advisory warning, after J.Lo, and the last to have one until the release of her eighth studio album, A.K.A., in 2014.

It garnered mixed reviews from music critics, but debuted atop the Billboard 200 in the United States, selling 156,000 copies in its opening week—the first remix album to reach the chart's top spot, and Lopez's second number-one album. The lead single "Ain't It Funny (Murder Remix)", featuring Ja Rule, reached number one on the Billboard Hot 100; and its second, "I'm Gonna Be Alright (Track Masters Remix)", reached the top ten. It also contained the song "Alive", which failed to chart. J to tha L–O! The Remixes became the fourth best-selling remix album of all time, after Michael Jackson, Madonna and Linkin Park's remix efforts. It has sold 1.5 million copies in the United States.
