Kenneth Farnes was an English cricketer. He played in fifteen Tests from 1934 to 1939.
Farnes was born in Leytonstone, Essex, and was educated at the Royal Liberty School in Gidea Park. He made his first-class debut for Essex in 1930, aged only 19. He took 5–36 in his second county match against Kent. He studied at Pembroke College, Cambridge, playing cricket in the University side for three years while also continuing to play for Essex. After graduating, he became a teacher at Worksop College, which limited his opportunity to play for Essex.
Farnes was reduced to tears in 1932, playing against Yorkshire at Scarborough. Earlier that year, playing at Leyton, Yorkshire had beaten Essex by an innings and 313 runs. Farnes reinforced Essex for the return match. Bowling as fast as he could, he conceded 75 runs to Herbert Sutcliffe and Maurice Leyland in 4 overs, and Essex lost again by an innings and 8 runs.
In 1933, he took 41 wickets for Cambridge at a bowling average of 17.39 runs; in all, he took 113 wickets at an average of 18.38 that year. He was called up for the 1st Test against Australia in 1934, at Trent Bridge, taking 5-102 and 5-77, although England lost by 238 runs.
