Rilo is a boy's and girl's baby name of uncertain origin, possibly from the Bulgarian word for the Rila Mountains — the highest range in the Balkans, home to the famous Rila Monastery. The mountain name may derive from an ancient Thracian word. Indie rock band Rilo Kiley made this unusual name familiar in the 2000s.
Rare and evocative of high mountain landscapes, Rilo is a name for parents drawn to unusual geographic names with natural beauty at their core.
Rilo has 8+ years of history in the U.S., first appearing in 2008.
