'''Buttermilk Channel''' is a small [[tidal strait]] in [[Upper New York Bay]] in [[New York City]], approximately {{Convert|1|mi|km}} long and {{convert|0.25|mi|km}} wide, separating [[Governors Island]] from [[Brooklyn]]. The channel is marked by a number of navigation aids (green cans no. 5 and 7 at the northeast entrance, and green gong no. 1, marking low water off the tip of Governors Island).  Tidal currents on the channel are rather strong.
