Jack Sullivan (born November 1999) is a British sports executive who is currently a director at West Ham United. He is the son of former West Ham chairman David Sullivan.

Social media and journalism Sullivan first came to public attention following his controversial use of Twitter to discuss West Ham United's club affairs and transfers. In 2013, commenting on the signing of Marouane Chamakh, Sullivan wrote "I am very sorry about this news Chamakh has sign a 6 month loan deal! not my pick :(". In 2015, Sullivan posted a picture of West Ham manager, Sam Allardyce laughing in a tweet mocking West Ham rivals, Millwall following their relegation to League One.

Sullivan was criticised by Graeme Souness for his use of Twitter. Souness wrote in The Times that the use of Twitter to criticise the manager's selections, substitutions and signings was unacceptable. Former West Ham manager, Sam Allardyce, blamed owner David Sullivan for giving the information to his son and for allowing him to tweet it.

Sullivan also wrote a column called The Insider on West Ham's website. This discussed transfer targets and fees and was pulled from the club's official website on the orders of West Ham's managing director, Karren Brady after she had been inundated with complaints from supporters.
