The name is believed to derive from the ancient Slavic word "olesya," which means "light" or "radiance." It is often associated with the sun, light, and warmth. In some variations of its pronunciation, Olesya may also be linked to the Greek goddess Hecate. The name has gained popularity in other parts of Eastern Europe as well, including Belarus and Bulgaria. In English, it is sometimes spelled or transcribed as Olesea or Olessia.
