Dahlmeier earned her second straight gold medal at these Olympics by winning the women's 10 pursuit at the Alpensia Biathlon Centre in PyeongChang, South Korea.
It is the first time in Winter Olympics history that a competitor has won both biathlon events, and is the first athlete to pick up two medals during the Pyeongchang games.
With that tally of golds he joins alpine skier Jean-Claude Killy on three Olympic titles, a French all-time record.
Dahlmeier made the most of it, speeding away from her rival to open up an unassailable lead, stopping only to fire off a final salvo of five flawless shots before cruising to victory.More news: Winter Olympics opening ceremony sees Intel use record 1218 drones
She said: "It feels really great, it's wonderful. I just stuck to my plan, and I was so happy when I crossed the finish line", she told reporters.
Dahlmeier missed just once in her four visits to the shooting range to help her hold off Anastasiya Kuzmina, who claimed the silver medal. I felt really, really exhausted before the race and also during the race in the first laps.
It was Dahlmeier's coolness on the range that saw her to victory in the end.

"It's always, always about your mind, it's always about if you believe and today it was for (a) sure really good fight for gold but for silver I am also happy".
"I took a bit more time than my opponent to shoot my first ammunition, then when I realised that I'd shot clean, I knew I was the only one who would decide who would be the Olympic champion".
The German's absence from the head of the pack did not last long, however, and Kuzmina's hopes were dashed when she missed two targets amid strong winds at the third shooting stage.
Meanwhile, bronze medallist Bescond acknowledged that Dahlmeier had raised the bar to new levels for her fellow biathletes this season.More news: Kim Jong-un Invites South Korean President to Pyongyang
