Jack David Shantry (born 29 January 1988) is a former English cricketer who played county cricket for Worcestershire. He is now an umpire.

Shantry played for Shropshire Under-17s as early as July 2004, scoring 64 at the top of the order against Yorkshire Under-17s.^[1] He made several further appearances for Shropshire Under-17s, and also played for Shrewsbury Cricket Club, appearing in the Cockspur Cup and making an appearance against Kidderminster Victoria in the Birmingham and District Premier League.^[2]

In 2007 and 2008, Shantry progressed to a mixture of senior cricket at minor counties level with Shropshire County Cricket Club and Second XI cricket for Worcestershire. He took 7/34 for Worcestershire Second XI against Leicestershire II in June 2008,^[3] and scored 88 for Shropshire against Wales Minor Counties in August of the same year.^[4] Between these two feats, in July, he had appeared for Shropshire in the final of the Resource Bank Twenty20 Cup, which they lost to a star-studded Lashings World XI side despite Shantry's 3/11.^[5]

Shantry made his senior debut for Worcestershire in a Pro40 match against Essex at Colchester on 23 August 2009, taking the wicket of Ravi Bopara and not batting.^[6] Two days later, he made his maiden appearance in first-class cricket when he was selected for Worcestershire's County Championship clash with Nottinghamshire at New Road. In a drawn game, Shantry claimed the wickets of Bilal Shafayat and Mark Ealham, but was lbw for nought in his only innings.^[7] He retained his place in the side in both one-day and four-day cricket, and so his club cricket appearances, now for Walsall, became less frequent.^[2]

Shantry pressed his claims for a regular place in the side in his first game of the 2010 season, a non-first-class warm-up match against Bradford/Leeds UCCE. He claimed 5–18 in the first innings, and opened the bowling in the second innings, taking a wicket with the first ball of the innings and finishing with 7–47, to complete a match haul of 12 wickets for 65. Worcestershire went on to win the game.^[8]

In September 2014, he scored his maiden first-class century (and took ten wickets in a first-class match for the first time) in a victory over Surrey that guaranteed Worcestershire promotion to Division 1.^[9]

In June 2018, Shantry announced his retirement from all cricket with immediate effect, due to ongoing back injuries. In 2022, Shantry became an umpire.^[10]
