%X In this study, the antibacterial and antioxidant activities of the lichen species Ramalina calicaris (L.) Fr. were investigated. Lichen samples belonging to Ramalina calicaris were collected from two different locations (Mudurnu-Alada£¿lar) in Bolu. After the separation and the identification steps, the samples were washed, dried and then extracted using an acetone solvent. Antibacterial activities of the acetone extracts were investigated by disk diffusion method on two Gram negative (CECT 4122 Pseudomonas aeruginosa, ATCC 25922 Escherichia coli) and two Gram positive (ATCC 29212 Enterococcus faecalis, ATCC 25923 Staphylococcus aureus) bacteria. As a result of the study, the both extracts of lichen samples collected from two different locations in Bolu had antibacterial activity on only Gram positive E. faecalis and S. aureus. However, they did not show a great difference between their antibacterial activities. Antioxidant activity studies were also carried out with R. calicaris samples collected from Bolu-Alada£¿lar location, which indicated relatively higher antibacterial activity by using CUPRAC method. It has been found that R. calicaris acetone extract has antioxidant activity as it has a certain level of chromogenic oxidant reduction capacity
