Johan Deysel (born 26 September 1991) is a Namibian professional rugby union player who plays as a centre for Pro D2 club Colomiers and captains the Namibia national team.

He joined the Potchefstroom-based Leopards rugby union and represented them in the Under-21 Provincial Championship in 2011 and 2012, as well as playing for university side NWU Pukke in the Varsity Cup competition.

[10] He also started their semi-final match – facing the Falcons for the second week in a row – but could not prevent his side losing 24–31 to be eliminated from the competition.

[12] He also scored a try against the UFS Shimlas in the final, but it proved futile as the team from Bloemfontein won 63–33 to be crowned Varsity Cup champions.

However, due to Deysel's involvement with Namibia at the 2015 Rugby World Cup, he played no part in the rest of their season.
