Markram enjoyed a breakthrough first-class debut season in 2016/17, having amassed 565 runs at an average of 51.36, including two centuries and two fifties.
The 22-year-old, who scored a match-winning 161 in the Momentum One-Day Cup Final in March, will also serve as vice-captain for both limited-over competitions, under current captain Albie Morkel.
Markram has previous captaincy experience, having led South Africa Under 19s to World Cup glory in 2014. Most recently, he captained the South Africa ‘A’ four-day side against the England Lions in June, before leading the side against India ‘A’ in last month’s two-match home series.
The opening batsman says he is looking forward to the challenge of his maiden season in charge.
Markram said: “It’s a massive honour for me as a young player to lead the quality players that are amongst the Titans squad. There’s plenty of experienced players in the changing room, so I will try and absorb as much information from them as possible to ensure the team goes in the right direction.
“Henry was brilliant in what he did – he’s a great leader and there are a few attributes I will look to take from him. I am young and I will make mistakes but as long as I can keep experienced players close to me, I believe that I will make enough right decisions.”
Markram has experienced a whirlwind past 12 months, which culminated in his call-up to the South African Test squad against England during the winter months, but says his thoughts are focused on the Titans.
He added: “I will always have the team’s interest at heart and as long as the team does well, I will be happy. The goal will be to win the Sunfoil Series. We missed out on it last year and if I look at the cricket we played, I think we have more in the tank and I believe if we play to our potential as a side we will be challenging for the trophy.”
