A bicycle front derailleur is basically provided with a base member, a chain guide, a link mechanism, and a biasing member. The base member is configured to be fixedly coupled to the bicycle. The chain guide is configured to guide a chain. The link mechanism couples the chain guide to the base member between retracted and extended positions in response to movement of an operation cable. The link mechanism includes a first link pivotally connected to the chain guide about a first pivot axis. The first link is configured such that the first pivot axis moves in a forward-rearward direction, while the chain guide moves between the retracted position and the extended position in a mounted state where the base member is mounted to a bicycle frame. The biasing member is operatively disposed between the base member and the chain guide to bias the chain guide towards the extended position.
