Sweden's Charlotte Kalla won the women's skiathlon to secure the first Gold Medal of Pyeongchang 2018.
Bjorgen's silver means that the 37-year-old now has a total of 11 medals.
Kalla won in 40 minutes 44.9 seconds to claim her third Olympic gold, while Finland's Krista Parmakoski was third.
"I was quite nervous today and the Olympics is something I have focused on for a long, long time," said Kalla.
"On the finish line. I did not want to look back and just focused on keeping pushing."
