NCIS: Hawai'i is the latest installment in the NCIS franchise, and with it comes a new set of cast and characters for fans to come to know and love. The cast of NCIS: Hawai'i ranges from major veterans to brand new names, all of which come together to form a cast of crime-solvers determined to keep the beautiful islands of Hawai'i safe. Here is a complete guide to the cast and characters of NCIS: Hawai'i.

As the fourth installment of the NCIS franchiseNCIS: Hawai'i follows a group of main-landers as they are transplanted to the NCIS Pearl Harbor station in Hawai'i. The station is helmed by special agent in charge Jane Tennant, who has been tasked with putting together a team to bring with her on her new assignment. Like the NCIS installments before it, NCIS: Hawai'i focuses on solving naval-based crimes. However, the new series also focuses on the balance between duty and family, the struggles of being a female agent in a male-dominated field, and the mysteries that are unique to Hawai'i.

NCIS: Hawai'i also marks the first time that a spin-off of the NCIS franchise has been helmed by a woman: Special Agent Jane Tennant. The closest the series has come before was the pilot for NCIS: Red, where Kim Rover co-starred; unfortunately, the pilot wasn't picked up to series. Now, Jane Tennant joins the likes of Special Agent Leroy Gibbs (Mark Harmon), Special Agents G. Callen and Sam Hanna (Chris O'Donnell and LL Cool J) and Special Agent Dwayne Pride (Scott Bakula) as the special agent in charge at NCIS Pearl Harbor.

Sometimes, that means Black Hawk helicopters interrupt her daughter's soccer games.
