Joachim of Osogovo () or Joachim Osogovski was a Bulgarian hermit, now a saint, a contemporary of Gabriel of Lesnovo and Prohor of PÃÂinja. Joachim was named after a mountain, the Osogovo, no differently than Prohor PÃÂinjski who, too, was named after a mountain, PÃÂinja.
When Joachim of Osogovo and Prohor of PÃÂenja were elevated to sainthood at Staro NagoriÃÂane in the church of St. George (built by King Stefan Milutin), the Bulgarian Orthodox Church was the first of that era to foster the cults of holy monks and hermits.
His feast day is celebrated on the 16th of August (Julian calendar).
