Woods 4: The Green Album is the third full-length album and fourth studio release by Ontario blackened doom metal band Woods of Ypres. It is the band's only release to feature guitarist Bryan Belleau, the only full album to feature Evan and Shane Madden on bass and drums, and the only full-length Woods of Ypres release to not feature frontman David Gold on drums. It is the band's only full-length album to be released on Gold's final independent label Practical Art Records, and its March 2011 reissue through Earache Records marked their debut on that label as well. 

A music video (the band's last) was released for the song "I Was Buried in Mount Pleasant Cemetery". A limited run of 1,000 copies of Woods IV also included a bonus album: Slaughter of the Seoul, the final album by South Korean death metal band Necramyth, who Gold drummed for at the time
