Mark Jansen was a HouseGuest on Big Brother 19 (US).

Mark is mostly known for being part of a showmance with Elena Davies known as "Marlena" and for being one of the the stronger competitors of the season. Mark was put in the middle frequently when the house turned on his closest allies Cody Nickson and Dominique Cooper. He tried to remain in good graces with the house but it proved to be impossible and some of his housemates accused him of "flip flopping." Mark also frequently clashed with fellow houseguest Josh Martinez, throwing pickle juice and hot sauce in Josh's face after a game of pool and Josh harassing Mark by banging pots and pans nearly resulted in a physical altercation. He was targeted for associating too much with Jessica Graf and Cody and in doing so put a strain on his relationship with Elena. The group was picked off by the rest of the house starting with Jessica, then Cody and Elena during a Double Eviction which left Mark alone in the game with no allies. Mark saved himself from being evicted prior to this by winning a Power of Veto or Temptation Competition four weeks in a row but his winning streak came to an end in week 8. He was voted out for being too big of a threat in competitions and became the third member of the jury. Mark was one of the few houseguests to catch on to Paul Abrahamian playing a manipulative and highly strategic game. He attempted to recruit Jason Dent to make a move against Paul but Jason remained loyal to Paul only to be evicted because of him two weeks after Mark. In jury Mark, Elena, Cody, Alex Ow and Jason all agreed Paul overplayed and failed to manage the jury so they voted Josh the winner.

Since the show ended Mark moved to Texas where he currently lives with Elena, started his own fitness program and Youtube channel "Mark Jansen" where he advocates against bullying and living a healthier lifestyle.

  • Mark is the first HouseGuest to win immunity through the Temptation Competition.
    • He is also the only HouseGuest to win twice. Ironically he was nominated the week after his safety was up both times, however he also won the Veto and saved himself both times.
    • He is also the only HouseGuest to take an apple from the Tree of Temptation.
  • Mark is the second HouseGuest to win the PoV twice in Big Brother 19, following Paul.
  • Mark is tied with fellow HouseGuest Josh Martinez, Big Brother 11 HouseGuest Michele Noonan, Big Brother 15 HouseGuests Helen Kim and Elissa Slater, and Big Brother 18 HouseGuest Corey Brooks for the most weeks spent as a Have-Not in a single season with four.
    • However, his 4th time being a Have-Not was cancelled due to winning the Have-Not Escape, so his 5th time counts as his 4th week.
