'Bushey' means an enclosure made of bushes.
It comes from Old English bysc, bush or thicket, and hæg, enclosure, though the name has been debated. The Domesday Book of 1086 records it as Bissei. The station opened in 1841, became Bushey & Oxhey around 1912 and plain Bushey in 1974, although it stands in Oxhey, which was first called New Bushey after the older village.
