Golowan is the Cornish language word for the Midsummer celebrations in Cornwall, UK; widespread prior to the late 19th century and most popular in the Penwith area and in particular Penzance and Newlyn.

The midsummer bonfire ceremonies were revived at St Ives in 1929 by the Old Cornwall Society and since then spread to other societies across Cornwall, as far as Kit Hill near Callington. Since 1991 the Golowan festival in Penzance has revived many of these ancient customs and has grown to become a major arts and culture festival; its central event 'Mazey Day' now attracts tens of thousands of people to the Penzance area in late June.

The ceremony of Crying The Neck took place before the feast, the neck being formed into a Corn dolly, which presided over the celebrations. Since 2008 a revived Guldize celebration has been held in Penzance and since 2010 in several other locations across Cornwall.
