William Quarles (1800–1879) was an English first-class cricketer associated with Norfolk who was active in the 1820s. He also played for Suffolk. Quarles' batting style is unknown.

Quarles made a single first-class appearance for Norfolk against the Marylebone Cricket Club (MCC) at Lord's in 1820.^[1] The MCC scored 473 all out in their first-innings, in response Norfolk managed just 92, with Quarles batting at number eleven and ending unbeaten on 0. The MCC fared less well in their second-innings with a total of 108. This gave them a lead of 489 over Norfolk, which was more than enough as Norfolk were dismissed for 72, with Quarles himself making 2 runs before he was dismissed by William Ward. The MCC's final margin of victory was 417 runs.^[2] A decade later he appeared in his second first-class match, this time for Suffolk against the MCC at Field Lane, Bury St Edmunds.^[1] The MCC made 100 all out in their first-innings, with Suffolk making 74 in response, with Quarles being dismissed for a duck by Herbert Jenner. The MCC were bowled out for 68 in their second-innings, leaving Suffolk with a total of 95 to chase. However, Suffolk well just short in being bowled out for 82, with Quarles contributing 4 to the total before he was dismissed by Ned Wenman.^[3]
