Maximos is of Greek origin, derived from the word 'megistos', which means 'greatest'. It is a masculine given name that was borne by several early Christian saints and martyrs, most notably Saint Maximos the Confessor, a theologian and monk who lived in the 7th century. The name has been used throughout history among Christians of Eastern Orthodox faith, but it has also been adopted by other communities over time. In some cultures, it may be anglicized to Maximus or Maximilian.
The name Maximos experienced significant popularity in the early 2000s with a peak of 58 births in 2002, but has since declined steadily to an average of around 10-20 births per year from 2017 onwards.
