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 and actor. Big Pun emerged from the underground hip hop scene in The Bronx borough of New York City, in the late 1990s. He first appeared on albums from The Beatnuts, on the track "Off the Books" in 1997, and on Fat Joe's second album Jealous One's Envy in 1995, prior to signing to Loud Records as a solo artist. Pun's lyrics are notable for technical efficiency, having minimal pauses to take a breath, heavy use of alliteration as well as internal and multi-syllabic rhyming schemes.

About.com ranked him #25 on its list of the 50 Greatest MCs of Our Time (1987–2007), while MTV2 ranked him #11 on its list of the "22 Greatest MCs." In 2012, The Source ranked him #19 on their list of the Top 50 Lyricists of All Time. An article from The Rolling Stones Magazine states, "Pun embodied all of the traits of a master wordsmith: melody, a unique flow, an unforgettable voice, humor, and lyrics that made other MCs go back to their black and white composition notebooks."
