Sticta tunjensis is a species of foliose lichen in the family Peltigeraceae. Found in Colombia, it was formally described by Bibiana Moncada and Robert Lücking in 2012. The type specimen was collected in (Tunja, Boyacá Department) at an altitude between 3065m–3085mm (10,056feet–10,121feetm). The lichen is only known to occur in the Andes of Colombia at altitudes between 1900mand3080mm (6,200feetand10,110feetm). It has been found growing on both bark and on soil, and it often grows among liverworts in genus Plagiochila. The specific epithet tunjensis refers to the type locality. Sticta tunjensis is somewhat similar to Sticta weigelii in morphological features, but it is phylogenetically distinct.
