# Lista de membros do elenco de Grey's Anatomy

Grey's Anatomy é uma série de televisão americana de drama médico exibida no horário nobre da rede ABC. Seu episódio piloto foi transmitido pela primeira vez em 27 de março de 2005 nos, Estados Unidos. Ao criar o show, os produtores colocam ênfase no processo de fundição. A série se encontra em sua décima sétima temporada, com cerca de 15 episódios e concentra-se na trajetória profissional dos médicos fictícios do Grey Sloan Memorial Hospital (anteriormente Seattle Grace Mercy West e Seattle Grace), enquanto tentam manter vidas pessoais. A premissa do show se originou com Shonda Rhimes, que é produtora executiva, junto com Betsy Beers, Mark Gordon, Krista Vernoff Rob Corn, Mark Wilding e Allan Heinberg. É filmado principalmente em Los Angeles, Califórnia.
A série foi criada para ser racialmente diversificada. Todos os papéis da série são lançados sem que as raças dos personagens sejam pré-especificadas, de acordo com a visão de diversidade de Rhimes. A protagonista da série, Meredith Grey, é interpretada por Ellen Pompeo. Pompeo estrelou como o papel principal em Moonlight Mile, o que explica o significado de ela ser escalada como Meredith. Dra. Grey foi designada para trabalhar sob as ordens de Miranda Bailey a única personagem desenvolvida com uma descrição racial em mente, que é interpretada por Chandra Wilson. Na adição de Wilson ao elenco, Rhimes relatou: "[Wilson] é exatamente quem é Miranda". Os outros internos que trabalharam com Meredith sob os cuidados de Bailey são Cristina Yang, George O'Malley, Izzie Stevens e Alex Karev interpretados por Sandra Oh, T.R. Knight, Katherine Heigl e Justin Chambers respectivamente. O personagem de Chambers não era originalmente parte do piloto, mas foi adicionado mais tarde como o quinto e último interno. Oh foi inicialmente trazida para interpretar a personagem de Bailey, mas pressionou para fazer o teste para o papel de Cristina. Muitos atores fizeram o teste para o papel do Dr. Derek Shepherd incluindo Isaiah Washington, mas quando Patrick Dempsey fez o teste, "ele era simplesmente perfeito", de acordo com Rhimes. Washington foi escalado como Burke, porque o ator original para interpretar Burke teve que se retirar.
A segunda temporada marcou a introdução de Eric Dane como o principal cirurgião plástico Dr. Mark Sloan e Sara Ramírez como a residente Dra. Callie Torres. Eles foram inicialmente escalados como personagens recorrentes, mas ambos receberam o papel principal na abertura da terceira temporada. Ramírez foi escalada após executivos da ABC lhe oferecerem um papel no programa da rede de sua escolha, Dane já tinha feito um teste sem sucesso para um papel no episódio piloto. Kate Walsh também se juntou ao show na segunda temporada, depois de fazer uma aparição na primeira temporada como a Dra. Addison Montgomery a esposa distante de Derek. Walsh deixa o show no final da terceira temporada, a fim de protagonizar seu próprio drama médico, o primeiro spin-off de Grey's Anatomy, Private Practice. Burke parte no final da terceira temporada e é substituído por Erica Hahn, interpretado por Brooke Smith, que deixa o show durante a quinta temporada. Chyler Leigh, aparece pela primeira vez na terceira temporada como a meia-irmã de Meredith, Lexie Grey.
Kevin McKidd, interpretando o Dr. Owen Hunt foi promovido ao elenco regular na quinta temporada) depois de originalmente ser escalado para um arco de história específico. Jessica Capshaw recebe o status de regular no início da sexta temporada, depois de interpretar a pediatra Arizona Robbins na 5ª temporada. Após a morte de O'Malley e a saída de Stevens, Jesse Williams e Sarah Drew juntaram-se ao elenco como novos residentes do Mercy West Jackson Avery e April Kepner ambos tendo feito sua estréia na série como personagens recorrentes na sexta temporada. Kim Raver que interpreta a Dra. Teddy Altman foi promovida a membro regular no final da sexta temporada depois de fazer participações recorrentes.
Na décima temporada, o novo lote de internos introduzidos durante a nona temporada foram feitos personagens regulares, sendo eles: Camilla Luddington como Dra. Jo Wilson, Gaius Charles como Dr. Shane Ross, Jerrika Hinton como Dra. Stephanie Edwards e Tessa Ferrer como Dra. Leah Murphy. Tina Majorino que interpretava a Dra. Heather Brooks não foi promovida pois sua personagem morreu durante os dois primeiros episódios da décima temporada. Após a conclusão de Private Practice, Caterina Scorsone foi promovida a membro regular para continuar seu papel como Dra. Amelia Shepherd, uma das quatro irmãs do Dr. Derek Shepherd. Scorsone interpretava a Dra. Amelia Shepherd desde a sétima temporada com pequenas participações. Kelly McCreary como Dra. Maggie Pierce foi promovida a regular depois de ser creditada como estrela convidada até o décimo primeiro episódio da décima primeira temporada. O elenco recebeu inúmeros prêmios e indicações, incluindo um Screen Actors Guild Award de Melhor Performance de um Ensemble em Série Dramática, um Prêmio Globo de Ouro de Melhor Série de Televisão, e numerosas nomeações do Primetime Emmy Award para membros individuais do elenco.
