The story of Cassie

Cassie is a pet form, made from Cass with the familiar “-ie” ending. It is usually a short form of Cassandra, the Trojan prophetess of Greek legend, or of Cassidy. Like many pet forms it is now often given as a full name.

The CSO counts Cassandra and Cassidy as separate names.

Cassie first appears in the CSO records in 1984. The most babies came in 2009, with 33, and its best rank was number 145 in 2023. It is more popular in Northern Ireland, where it reached number 55 in 2023. In 2025 the two lists met in an unusual way, with 29 girls named Cassie in each.
