Cronk Urleigh (in Manx: Keeil Pharlane formerly Reneurling - the hill or ridge of slaughter) is a corner situated at the 13th Milestone roadside marker on the Snaefell Mountain Course used for the Isle of Man TT races on the primary A3 road in the parish of Michael in the Isle of Man. The nearby small hillock at Cronk Urleigh is traditionally thought to be the site of the original Tynwald courts until 1422, although the site may have been situated at nearby Rhencullen in Kirk Michael.
The corner at Cronk Urleigh was part of the Highland Course and the Four Inch Course used for the Gordon Bennett Trial and Tourist Trophy car races held between 1904 and 1922. Cronk Urleigh was part of the St John's Short Course used between 1907 and 1910 for the TT races, and became part of the Snaefell Mountain Course used since 1911 for the TT and from 1923 for the Manx Grand Prix races.
