Kaimaktsalan is a mountain on the border between Greece and the Republic of Macedonia. It is the southernmost and highest peak (2521 m) of a range known in Greek as the Voras Mountains and in Macedonian as Nidže. The national frontier between the two countries runs across the summit. It is the third highest peak in Greece after Mount Olympus and the fifth highest in the Republic of Macedonia.
Ottoman Turkish origin inspired by its white, snowy peak: kaymakçalan means 'kaimak beater'.
