Welsh rhod, "wheel", and rhi, "ruler" — wheel ruler. Rhodri Mawr united most of Wales in the ninth century.
Rhodri was given to 36 babies in England and Wales in 2025. Its best year was 1998, with 59 registrations. The name is absent from American records, so there is no US curve to compare it against.
