Robert James Hamilton "Bob" Lambert (1874–1956) was an Irish cricketer. A right-handed batsman and a right-arm off spin bowler, he played 51 times for the Ireland cricket team between 1893 and 1930, including 23 first-class matches, captaining them on thirteen occasions. He also played first-class cricket for London County and Woodbrook Club and Ground. On his death, the Wisden Cricketer's Almanack described him as the best all-rounder produced by Ireland.
