John Alexander Robb (June 1, 1792 – January 28, 1867), was a 19th-century prominent shipbuilder at Fell's Point, Baltimore. He had his own shipyard, which became noted for fast sailing Baltimore Clippers. He was an apprenticeship under shipbuilder Henry Eckford. Abolitionist Frederick Douglass, as a young man, worked at the John A. Robb shipyard as a caulker for several years. Robb built the steamship Pulaski, that was lost off Cape Lookout in the 1838 Steamship Pulaski disaster. Robb died in Baltimore, Maryland in 1867.
