John B. Foster (1865–1930) was a New England artist, born in Gloucester on December 25, 1865. He was the son of John B. Foster, a fisherman who emigrated from England, and Sarah E. Merchant, daughter of a Cape Ann fishing family.
Foster worked primarily in watercolors depicting seascape and harbor scenes from the Gloucester area. Occasionally a work in oil becomes available at auction but his primary medium was watercolor. Examples of Foster's work can be seen in the Blackwood/March auction site and the Rockport Art Association web site.
