This research was carried out to determine the energy input-output analysis of lavender oil production. Data from agricultural farms in Isparta province was used. Energy input was calculated as 1993.89 MJ and energy output was calculated as 2925.51 MJ. Wood energy, fresh stalked lavender flower energy, equipment energy, human labour energy, electricity energy, and water energy inputs were 54.22 %, 41.86 %, 3.40 %, 0.23 %, 0.18 %, and 0.10 % of energy inputs, respectively. In this production, it is noteworthy that wood was used as fuel in the lavender oil production distillation process as the highest input. In the energy outputs, an average of 3.10 kg lavender oil and 130 kg lavender water were extracted by processing 234 kg fresh stalked lavender flower. Energy use efficiency, specific energy, energy productivity, and net energy for lavender oil production were calculated as 1.47, 643.19 MJ kg-1, 0.002 kg MJ-1 and 931.62 MJ, respectively.
