Robert Henry Lyttelton (18 January 1854 – 7 November 1939) was an English cricketer who appeared in seven first-class matches between 1873 and 1880. A member of the Lyttelton family who were prominent in English cricket in the mid to late 1800s, he did not play county cricket, but appeared for a number of representative sides, in which players were often chosen more for their social status than their cricketing ability. In his later years he was known for his views about sportsmanship in cricket, and he successfully campaigned for changes in the laws of the game to penalise blocking the wicket with the legs. He published two books about cricket and collaborated with others on two more.
