Meaning & origin

Lillien is a delicate floral name that emerged as an uncommon variant of the well-loved Lillian. First recorded in the United States in 1918, it saw its peak popularity in 2011, ranking around 13,000 nationally. While it remains rare, its spelling with an '-ien' ending gives it a slightly more modern and distinctive feel. The name has been on a falling trajectory since 2010, aligning with broader trends away from embellished spellings. At 1 in 267,878 newborns recent statistics place it firmly among the more unusual choices.

Lillien is most often considered a modern respelling of Lillian, itself a variant of Lilian, which may derive from Latin lilium 'lily' or from the Welsh name Lilwen (from lili 'lily' and gwen 'white, blessed'). The spelling with an '-ien' ending became popular in the United States in the late 20th century, part of a trend of creative respellings of traditional floral names.
