Morten Steenstrup (born 4 April 1953) is a Norwegian barrister and politician.
He was born in Tønsberg to Petter Chr. Steenstrup and Kari Bertnes. He was elected representative to the Storting for the period 1981 - 1985 for the Conservative Party, and reelected for the period 1985 - 1989.[1]
On 1 December 2021, he was designated as the new leader of the Oslo Conservatives after Heidi Nordby Lunde announced in October that she wouldn't be seeking re-election.[2] He was formally elected on 22 January 2022.[3] After leading the Oslo Conservatives to victory in the 2023 local elections, Steenstrup announced a week later that he wouldn't be seeking re-election as leader. He stated that he had aimed to secure his party an electoral victory before the end of his term, which he did ultimately accomplished.[4] Kapur formally succeeded him at the annual meeting on 27 January 2024.[5]
