"Thong Song" is the name of a 1999 song recorded by Dru Hill member Sisqó for the Def Soul label. The song was issued as the second single from Sisqó's Unleash the Dragon LP in February 2000, and was its second biggest hit.

The record is a novelty song celebrating, in a playful way, women who wear thong underwear and bikinis. The song's chorus was inspired by the Dragnet theme song, with its re-occurring hook of "thong-th-thong-thong-thong!"

"Thong Song" was a runaway hit; it reached #3 on the US pop charts, and made Sisqó arguably the biggest star in R&B music for the year 2000. It became the de-facto anthem of 2000 Spring Break, and was omnipresent for most of the spring of 2000. The success of "Thong Song" and its #1 pop hit follow-up, "Incomplete", propelled Unleash the Dragon to a selling-status of over four million copies.

The song was written by Sisqó and co-producers Tim Kelley and Bob Robinson. Songwriters Desmond Child and Robi Rosa receive songwriting credit because of the interpolation of part of their composition, Ricky Martin's "Livin' La Vida Loca", in the song's lyrics. "Thong Song" is based around a violin melody, similar to that in The Beatles' "Eleanor Rigby".

A remix, "Thong Song Uncensored", features a guest rap from Foxy Brown, and is included on the soundtrack LP for the 2000 Eddie Murphy film Nutty Professor 2: The Klumps.
