Kimberly Merle Schrier (/ˈʃraɪər/ SHRIRE; born August 23, 1968) is an American former physician and politician who has served as the U.S. representative for Washington's 8th congressional district since 2019. She is a member of the Democratic Party. Her district includes the suburbs east of Seattle, and extends across the Cascade Range to rural areas in central Washington, as well as the cities of Wenatchee and Ellensburg.

Schrier was born, and raised, in Los Angeles, California, where she graduated from Palisades Charter High School. She earned a bachelor's degree from the University of California, Berkeley, graduating Phi Beta Kappa with a degree in astrophysics. She attended the University of California Davis School of Medicine, where she earned her Doctor of Medicine degree. She continued on to a residency at the Stanford University School of Medicine.

Schrier's professional career as a pediatrician began in Ashland, Oregon, where she worked for one year before joining Virginia Mason Medical Center in Issaquah, Washington in 2001. While working at Virginia Mason, she became politically active, particularly on healthcare issues. In 2017, Schrier was dissatisfied with Congressman Dave Reichert's handling of the efforts to repeal and replace the Patient Protection and Affordable Care Act and this, coupled with her frustration with the results of the 2016 elections, led to her decision to enter politics.

Schrier announced her candidacy to represent Washington's 8th congressional district in August 2017, a year before the primary. She initially intended to challenge incumbent Dave Reichert, but the seat became open in September 2017 when Reichert announced his retirement. She had decided to run after the 2016 election, making the expansion of Medicare and the Affordable Care Act the centerpiece of her campaign.

No Democrat had ever been elected to represent the district and Reichert had been seen as a relatively safe incumbent, but his decision to retire left the seat as a potential Democratic pickup in an election year already leaning toward the Democratic Party.

Schrier advanced from the top-two primary, narrowly defeating attorney Jason Rittereiser, and advancing to face Republican Dino Rossi in the general election. The 8th district campaign attracted $25 million in spending, making it the most expensive in state history and one of the costliest nationally in 2018, including controversial attack ads from the Rossi campaign. One such ad nicknamed Schrier "Dr. Tax" and depicted her holding a large stack of $20 bills. The ad was perceived as antisemitic by The Washington Post.

Schrier won the general election with 52% of the vote. Although Rossi won 3 of the 4 counties in the district, Schrier won the district's portion of King County by nearly 30,000 votes, almost double her overall margin of 15,000 votes.

Schrier ran for reelection. She advanced from the top-two primary in first place and faced the second-place finisher, Republican U.S. Army veteran and Amazon senior project manager Jesse Jensen. Schrier won the general election with 51.7% of the vote.
