The genus Thymus (Lamiaceae) is represented by 38 species (64 taxa) in Turkey, and 24 of which are endemic to Turkey. Aerial parts of Thymus longicaulis subsp. chaubardii var. chaubardii, T zygioides var. lycaonicus, T longicaulis subsp. longicaulis var. subisophyllus and T pulvinatus collected from three different localities in Balikesir province were subjected to hydrodistillation to yield essential oils which were subsequently analysed by GC and GC/ MS. The main constituents of the oils were identified, and antimicrobial bioassay was applied. Thymol (56.6%, 42.8%, 36.9%) was the main component in the oils of T longicaulis subsp. chaubardii var. chaubardii (chemotype 1), T longicaulis subsp. chaubardii var. chaubardii (chemotype 11) and T zygioides var. lycaonicus respectively. The oil of T longicaulis subsp. longicaulis var. subisophyllus contained carvacrol (60.0%) and the oil of T pulvinatus borneol (27.9%) as main constituents.
