Nicholas Frederick Youngquest (born 28 July 1983) is an Australian model and former professional rugby league footballer. He played in the National Rugby League for the Cronulla-Sutherland Sharks, St. George Illawarra Dragons, Penrith Panthers and the Canterbury-Bankstown Bulldogs, and in the UK for the Gateshead Thunder, Celtic Crusaders and the Castleford Tigers, mainly as a winger.

Youngquest was born in Sydney, New South Wales, Australia.

Youngquest made his first grade debut for Cronulla-Sutherland in round 1 of the 2003 NRL season against Melbourne.

Youngquest then played for St George between 2004 and 2005. He played five games for the club in the 2005 NRL season as they finished second on the table but he did not feature in St. George's finals campaign.

Youngquest spent two seasons with Penrith in 2006 and 2007. His final year at Penrith saw the club finish last on the table and claim the wooden spoon.

In late 2007, Youngquest agreed to a one-year deal with the Wests Tigers, his fourth club in six years, but failed to make the NRL squad.

Youngquest was released midway through the 2008 NRL season and signed with Canterbury as a replacement for the released Cameron Phelps. He played four games for Canterbury in the 2008 season as the club finished last on the table.

After failing to make an impact in the NRL after six seasons, Youngquest moved to play for the French rugby league team Salanque Meditérrannée PIA XIII (also known as the Pia Donkeys) following the conclusion of the 2008 NRL season.
