Rex Orange County, IAMDDB, Khalid and Pale Waves also made the top five after 16 acts were long-listed in November.
Of winning BBC Sound Of 2018, Sigrid said: “It’s a lot to take in to have won something as prestigious as BBC Music Sound Of.
“I feel honoured as there are so many other artists I look up to who have won this before me, and honestly, I’m just really happy and proud of what my team and I have achieved together.
“I’m from a small town called Ålesund in Norway. I’m still 21 and it’s quite crazy to get this recognition.”
She added: “I’m very excited about the year ahead and sharing new music with everyone. I want to thank the panel for voting and the team involved in BBC Music Sound Of 2018.”
