The surname Kotsakis originates from Greece, with roots dating back to the Byzantine era. It is believed to have derived from the Greek word "kotsaki," which means a small bun or a small loaf of bread. This suggests that the name may have been initially associated with bakers or those involved in the production of bread.

During the Byzantine period, surnames were often based on occupations, physical characteristics, or places of origin. The earliest recorded instance of the name Kotsakis can be traced back to the 13th century, when it appeared in a manuscript from the Monastery of Vatopedi on Mount Athos, a significant center of Byzantine culture and learning.

In the 16th century, the Kotsakis name was found in various historical records from the Peloponnese region of Greece, particularly in the areas around Sparta and Kalamata. This suggests that the name may have originated or gained prominence in these regions during that time period.
