Daniel Lienert-Brown (born 9 February 1993) is a New Zealand rugby union player who currently plays as a loosehead prop for the Crusaders in Super Rugby.
Lienert-Brown attended Christchurch Boys' High School and played for the school´s first XV. His next step was to become a member of the Crusaders Knights development team in 2014. This put him in line for a call-up to the senior Crusaders side when a front-row injury crisis struck midway through the 2014 Super Rugby season. He was an unused substitute for the Crusaders home match against the Hurricanes on 28 April, but made his Super Rugby debut the following week as his side defeated the Lions 28-7 in Johannesburg.
Lienert-Brown was a member of the New Zealand Under 20 team which participated in the 2013 IRB Junior World Championship in France where he made 2 substitute appearances.
