A wynd (//) is typically a narrow lane between houses. The name is frequently encountered in towns and villages in Scotland and Northern England. The word derives from Old Norse venda ("to turn"), implying a turning off a main street, without implying that it is curved. In fact, most wynds are straight. In many places wynds link streets at different heights and thus are mostly thought of as being ways up or down hills.
The Old Town of Edinburgh had many wynds, such as St. Mary's Wynd, Blackfriars Wynd and Niddry Wynd, until Victorian street improvements in the 19th century led to their being widened and renamed "streets". 
Wynds feature prominently in the city centre of Aberdeen, a testament to the medieval street pattern in the city’s past. Before the levelling of St. Catherine’s Hill and the construction of Union Street, Back Wynd served as the main thoroughfare to and from The Green, the main point of entry into the city of Aberdeen in the early 1500s. Another medieval wynd still existing in the city centre, Correction Wynd, was built to link the top half of the city to its lower half.
In the East Neuk fishing village of Pittenweem in Fife, all walking connections between the shore and the raised beach—apart from the road down to the harbour—are wynds, namely: West Wynd, Calman's Wynd, Bruce's Wynd, School Wynd, Water Wynd and Cove Wynd.
