John Thewlis (30 June 1828 – 29 December 1899) was an English first-class cricketer, active 1862–75, who played for Sheffield and Yorkshire.
Thewlis came late into the game and was the second man to emerge from Lascelles Hall, Huddersfield, and play for his home county.
George Parr, successor to William Clarke in the management of the All-England Eleven, approached him for advice: "Greenwood, we are going to Southampton to play 22 there.
[citation needed] When Pullin finally did find Thewlis, "he was trudging on foot with a heavy basket of laundry clothes on his shoulder" and, at the end of the four-mile trek "was anxious to walk back again, as soon as possible, to earn a few coppers by getting in a load of coals".
In a subsequent volume, Talks with Old English Cricketers, Greenwood pronounced Thewlis "one of the best all-round men that ever Lascelles Hall turned out: he had strokes all round the wicket, and he was perfect in them all.
