Dee Dee Ramone (Douglas Glenn Colvin) (September 18, 1951[1] - June 5, 2002) was a German American songwriter and bassist, best remembered as a founding member of punk rock band The Ramones.

Dee Dee was also known for his distinctive count-in style, used to start off many Ramones songs.

Though nearly all of the Ramones' songs were credited equally to all the band members, Dee Dee was the group's primary lyricist and songwriter, penning songs such as "53rd & 3rd", "Commando", "Rockaway Beach" and "Poison Heart". He was the bass guitarist for the group from their formation in 1974 through 1989, although at first he wanted to play the guitar. He then left to pursue a short-lived career in rap music under the name Dee Dee King. Afterwards, Dee Dee returned to his punk roots and released three little-known solo albums featuring brand new songs (many were used later on Ramones records). Dee Dee also got married to Argentinian teenager Barbara Zampini, toured the world playing his songs, Ramones songs and some old favorites in small clubs and continued to write songs for the Ramones until 1996, when the band retired.

Dee Dee struggled with drug addiction for much of his life, especially heroin; he began using drugs as a teenager, and continued to use for the majority of his adult life. He seemed to clean up his act in the early 1990s and to remain clean for most of that decade until 2002, when he was found dead from a heroin overdose.
