The name Pastor is of Latin origin and means 'shepherd'. It's derived from the Latin word 'pastor', which also gives us the English word 'pastoral'. Traditionally, it has been used as a surname but in some cultures, particularly in Spanish-speaking countries, it's also used as a given name. The name gained prominence through its use as a title for religious leaders who tend to their flock, as Jesus is referred to as the Good Shepherd in the New Testament of the Bible.
"The name Pastor had a peak of popularity in the late 90s to early 2000s with several years seeing more than 6 births annually. However, it seems to have declined since then, with most recent years showing only 5 or fewer births each year."
