David Nucifora (born 15 January 1962) is a rugby union former player, coach and performance director.

In 2005 he joined the Auckland Blues team as a technical advisor and high performance manager, with the positions previously held by former All Blacks coach Graham Henry.

Deans’ decision to apply for the All Blacks made Nucifora the front runner for the Wallabies post, but the NZRU controversially decided to keep incumbent coach Graham Henry despite the All Blacks worst ever performance at a world cup which led to Deans successfully applying for the Wallabies job.

[citation needed] On 20 March 2008 Eddie O'Sullivan resigned from his post as Irish rugby manager.

[2] He is known in Ireland for his role in ensuring the supply of elite players to the professional pool, be they sourced internally or externally.

In 2021 he was criticised in a letter from the Irish women's rugby team, citing loss of trust in the union, and historic and systemic failings.
