The 2019 Bærum murder and mosque attack occurred on 10 August 2019 at the Al-Noor Islamic Centre in Bærum, Norway, about 20 kilometres (12 mi) west of the capital city Oslo. Philip Manshaus, a 21-year-old Norwegian man, murdered his 17-year-old adopted sister Johanne Ihle-Hansen at their home. He then drove to the mosque and shot his way through the glass door before opening fire, hitting no one. He was subdued by three worshipers after a scuffle and turned over to police. He attempted to livestream the shooting, but failed.

Manshaus was fixated on far-right conspiracy theories and mass shootings, and had been investigated in 2018 after a tip was filed over his neo-Nazi views. The tip was not followed up on, as it was deemed to be vague and lacked signs he was planning a violent attack. He murdered Ihle-Hansen due to her being of Asian ethnicity, and the mosque shooting was done to intimidate Muslims; the attack was inspired by the Christchurch mosque shootings, which had occurred earlier in the year. The guns were stolen from Manshaus's father.

Manshaus was convicted of murder and committing an act of terrorism, and in 2020 was sentenced to 21 years preventative detention, an order which, in Norway, can be extended indefinitely. The case was reopened in 2024, after experts assessed that Manshaus had likely been psychotic since 2017, including while the crime was committed.
