St Gobnet's Wood (alternative spelling: St. Gobnait's Wood) is a protected area of oak woodland at Baile Bhuirne, County Cork, Ireland. Along with Cascade Wood it is included in a fragmented Special Area of Conservation.
In 1998 St Gobnet's Wood was proposed as a Site of Community Importance under the EU Habitats Directive. The National Parks and Wildlife Service gave the area of the wood as about 30 hectares (ha). Subsequently, Cascade Wood, on the other side of the N22 road, was identified as the home of species protected under the Habitats Directive, notably the Kerry slug. In 2007 the Irish Environment Minister, John Gormley, proposed the expansion of the 'St Gobnet's Wood Special Area of Conservation' to include Cascade Wood. The European Environment Agency's records show the site as covering 44 ha on both sides of the main road, following an update in 2008.
When the Irish government gave protection to Cascade Wood, it was also agreed that the alignment of a proposed by-pass should avoid the SAC. As of 2013 the road in question, the new route for the Macroom-Baile Bhuirne section of the N22, had yet to be constructed.
