Down IV – Part II is the second EP by American sludge metal band Down. It was released in May 2014 via Down Records. It is the only release by the band featuring guitarist Bobby Landgraf, who replaced founding member Kirk Windstein in 2013, before Windstein returned to the band in late 2019. The album was recorded in frontman Phil Anselmo's home studio Nodferatu's Lair in Louisiana.
Part II was preceded by Part I in 2012. In certain territories (mainly Japan), both EPs were combined as a singular album under the title Down IV.
