Cierre is of Spanish origin and means 'closed' or 'finished'. It's often used as a masculine given name, though it can also be used for females. The name is popular in Spain and Latin America, but it has gained some traction internationally in recent years.
"Cierre was quite popular as a baby name from 1989 to 1992, with five babies named each year. There was a dip in usage in 1993 and 1994, but it rebounded slightly with six births in 1995."
