Rynard Jaco "Ligtoring" Landman (born 24 July 1986) is a South African rugby union footballer. He usually plays as a lock and occasionally as a flanker.
Landman played his youth rugby with the Leopards and that's where he began his senior rugby career. He played more than 40 games for the Potchefstroom-based side before joining the Boland Cavaliers in 2011. He only spent one season in Wellington before moving to the Griquas in 2012. Strong performances in the local Vodacom Cup and Currie Cup competitions allied to injuries to Martin Muller and Andries Ferreira saw him become an important member of the Cheetahs team that reached the play-offs in the 2013 Super Rugby season.
Landman signed for Welsh side Newport Gwent Dragons on a three-year deal prior to the 2014–15 Pro12 season.
