Carla Espinosa, RN is a fictional character in the American comedy-drama Scrubs, portrayed by Judy Reyes.

Carla appeared in every episode during the first eight seasons except three Season 8 episodes, "My Happy Place", "My Cookie Pants", and "My Full Moon". She worked as the head nurse at Sacred Heart Hospital, in which the main action of the show takes place.

Judy Reyes was a regular cast member for the first eight seasons, and is the only original cast member not to return for season nine, though her character was still mentioned. According to Donald Faison, who plays Carla's husband Christopher Turk, Carla becomes a stay-at-home mother following the birth of their second daughter, explaining the character's absence from season nine. She returns in the tenth season in a recurring role.

Judy Reyes describes her character as "sassy, no nonsense". Reyes relied on her sister, a real-life licensed nurse, as an inspiration for character, and to address technical questions Reyes had about nursing and medicine. After watching an episode, Reyes' sister commented, "You stole my character!", referring to Reyes emulating her personality.

Carla was born in the Dominican Republic but moved to Chicago while still a child. All her family is from the Dominican Republic, despite Turk's frequent and incorrect assertions that she is Mexican or Puerto Rican. It is revealed in Season 5 that she is 36 years old. It is also revealed in the episode "His Story" that Carla's father ran out on the family when Carla was a child.

Carla starts dating Christopher Turk (Donald Faison) in the show's second episode, "My Mentor". They remain together for the entire run of the show. Carla marries Turk in the season finale of season 3, "My Best Friend's Wedding". She and Turk go through a trial separation in season 4 after Carla discovers that Turk is still talking to his ex-girlfriend without telling her he is married. The situation gets worse when she and J.D. share a drunken kiss. Following some couples' therapy and some frank discussions with Turk and J.D., however, the couple reunites. Despite these issues, Judy Reyes believes the characters were made for each other, and set an example for other couples on the show to emulate.

Soon after reconciliation, they start trying to have a child. Initially, they are unsuccessful, but she finally gets pregnant toward the end of the season after several episodes are spent on Turk and Carla worrying about their respective fertility. Carla gives birth to a girl, whom they name Isabella, in the episode "My Best Friend's Baby's Baby and My Baby's Baby". J.D. becomes the godfather of the child. In "My Coffee" when J.D. enters the room that Carla's in with Isabella in her arms, she points to him and says "Isabella, this is the man you will be competing with for your father's love." In "My House", it is revealed that she suffers from post-partum depression. She spends most of the following episode in denial about the condition, but finally gets help after a frank discussion with Jordan Sullivan, who had also suffered from the condition.

Carla announces that she is pregnant for the second time in "My Absence".
