Christopher Lee Rios (November 10, 1971 – February 7, 2000), better known by his stage name Big Pun (short for Big Punisher), was an American rapper. Emerging from the underground hip hop scene in the Bronx, he came to prominence upon discovery by fellow Bronx rapper Fat Joe, and thereafter guest appeared on his 1995 album Jealous One's Envy.

Big Pun signed with Fat Joe's label, Terror Squad Productions and Loud Records in 1997 to release his debut studio album, Capital Punishment (1998) the following year. Met with critical acclaim and commercial success, the album earned a nomination for Best Rap Album at the 41st Annual Grammy Awards, peaked at number five on the Billboard 200, and became the first hip hop recording by a Latino solo act to receive platinum certification by the Recording Industry Association of America (RIAA). His second album, Yeeeah Baby (2000) peaked at number three on the Billboard 200, although Pun died two months before its release.
