Roger Hugh Cook (born 20 August 1965) is an Australian politician serving as the 31st and current premier of Western Australia since 2023.

He is the youngest of seven children born to Hugh David Cook, a child psychiatrist, and Lynette Ada Owen, an early childhood educator.

[3] After graduating, Cook worked in the offices of a number of Labor MPs, including Stephen Smith, Jim McGinty, and Chris Evans.

[5] Adams had unsuccessfully attempted to gain Labor pre-selection, and later accused Alan Carpenter of "parachuting" Cook into the seat.

[citation needed] Cook was responsible for a high-profile portfolio as minister for health from 2017 to 2021, particularly following the outbreak of the COVID-19 pandemic in Australia in early 2020.

He assumed the portfolio of Tourism, while retaining his status as Deputy Premier, and the ministries of State Development, Jobs and Trade, and Commerce and Science.

[12] Following the resignation of McGowan as premier in May 2023, Cook was the first minister to announce his intention to stand in the ensuing leadership ballot.

[13] 26 Labor MPs affiliated with the United Workers Union held a meeting on 30 May, choosing to support Sanderson over Cook, 17 votes to 11.
