Meaning & origin

Mega is a modern, ultra-rare name that first appeared in U.S. birth records in 2015. It reached its peak rank of #6143 in 2023, with a 1-in-122,005 rate, before declining in use over the following two years. The name has no recorded Top States or historical roots, placing it squarely in the category of contemporary inventions. Its brevity and energetic sound may appeal to parents seeking a distinctive, short name with a hint of grandeur, though its meaning remains open to interpretation.

Mega first appeared in U.S. records in 2015. It is almost certainly a modern coinage, perhaps derived from the Greek-derived prefix 'mega-' meaning 'large' or 'great', or as a playful respelling of Megan. It has no historical usage as a given name before the 21st century.
