Rockland is of American origin, derived from the English surname 'Rockland,' which was itself an early topographic name for someone who lived near a rock-strewn area of land. It consists of two elements: 'rock' meaning 'crag or rocky hill,' and '-land,' referring to 'tract of land.' The name became popular as a given name in the United States during the mid-20th century.
