John Ashby Lester was an American cricketer, active in the late 19th and early 20th centuries, and a teacher. Lester was one of the Philadelphian cricketers who played from the end of the 19th century until the outbreak of World War I. His obituary in Wisden Cricketers' Almanack, described him as "one of the great figures in American cricket." During his career, he played in 53 matches for the Philadelphians, 47 of which are considered first class. From 1897 until his retirement in 1908, Lester led the batting averages in Philadelphia and captained all the international home matches.

The Philadelphian cricket team was a team that represented Philadelphia, Pennsylvania, in first-class cricket between 1878 and 1913. Even with the United States having played the first ever international cricket match against Canada in 1844, the sport began a slow decline in the U.S. This decline was furthered by the rise in popularity of baseball. In Philadelphia, however, the sport remained very popular and from the end of the 19th century until the outbreak of World War I, the city produced a first class team that rivaled many others in the world. The team was composed of players from the four chief cricket clubs in Philadelphia–Germantown, Merion, Belmont, and Philadelphia. Players from smaller clubs, such as Tioga and Moorestown Cricket Club, and local colleges, such as Haverford and Penn, also played for the Philadelphians. Over its 35 years, the team played in 88 first-class cricket matches. Of those, 29 were won, 45 were lost, 13 were drawn and one game was abandoned before completion.
