Richard Castle (Nathan Fillion) is a well-known author, who, after having just killed off his most famous character and being nagged by his publisher ex-wife, is pulled in by NYPD Detective Kate Beckett to help with a copy-cat case and discovers a new source of inspiration. Castle now has the opportunity to use his knowledge and skills to help solve murders.
Detective Kate Beckett (Stana Katic) is a homicide detective with the NYPD. She is a first-class investigator who has gained a reputation as a detective who's intrigued by unusual cases. She joined the force after her mother was murdered and the case was not solved. She is forced to be shadowed by Castle, but the two make a great team.
Javier Esposito (Jon Huertas) works in the homicide division with Kevin Ryan as part of Beckett's team. He is always ready with a sardonic comment to keep Beckett on her toes and enjoys the way Castle riles her up. He and Ryan are friends, even though he is constantly arguing about obscure facts with Ryan.
Kevin Ryan (Seamus Dever) also works alongside Esposito as part of Beckett's team. He and Esposito regularly tease Beckett, but they are incredibly protective of her and ultimately treat her like one of the guys.

Lanie Parish (Tamala Jones) is a medical examiner who has a friendly outlook. As a friend of Beckett's, she is one of the few people with whom Beckett can let her guard down. She is also one of the few people who notices the personal connection between Beckett and Castle, and urges her to act on it.
Roy Montgomery (Ruben Santiago-Hudson) is Beckett's boss who appreciates Beckett's determination and diligence but maintains a close watch to make sure the investigation goes smoothly. He is amused by how much Castle annoys Beckett, but also appreciates how effective the two are when they work together.
Alexis Castle (Molly Quinn) is Castle's fifteen-year-old daughter who gets along better with adults than with kids her own age and enjoys school.
Martha Rodgers (Susan Sullivan), a former Broadway actress, is Castle's mother and lives with him and her granddaughter Alexis.
