Callandra "Cally" Tyrol (née Callandra Henderson) (also known as Cally or Crewman Cally, Deckhand Cally, or Specialist Cally) is a fictional character from the re-imagined Battlestar Galactica series. She is played by actress Nicki Clyne.

Cally works as an air maintenance Specialist on Galactica's flight deck and is married to her boss, CPO Galen Tyrol.

Cally joined the Colonial Forces to help pay for schooling as a dentist and was about to be honorably discharged following Galactica's decommission. The destruction of the Twelve Colonies changes these plans, leaving her little choice but to stay on board as a member of the crew.

As with many secondary characters in the series, it was never definitively stated which of the Twelve Colonies that Cally was from, however there are several clues. In the episode "Dirty Hands" she criticizes the social position of the enlisted crewmen like her and her husband by pointing out that most Colonial Fleet officers are from the wealthy colonies like Caprica, Tauron, and Virgon - as opposed to from the poorest colonies, which she lists as Sagittaron, Gemenon, and Aerilon. This indicates that she was from one of these poorer colonies and not one of the wealthier ones. However, she does not appear to be from the poorest and most downtrodden colony, Sagittaron, because at various points when the Sagittarons are discussed she refers to them as a separate group. It's not clear if this means she was from Gemenon or Aerilon, or one of the other six "not wealthy" colonies, though her husband was a Gemenon.

Prior to the attack, and immediately following it, she works as a Specialist in the air maintenance crew of Battlestar Galactica. The crew is led by Chief Galen Tyrol, on whom she has a secret crush despite his relationship with Sharon "Boomer" Valerii. While on the Chief's crew, she is responsible for the maintenance of Vipers and Raptors, and sometimes Galactica herself.

Cally gets her first experience with the hazards of field operations when she is assigned to a team sent to the prison ship Astral Queen to enlist volunteers from the inmates for water recovery from an icy moon. While the team is there, the prisoners stage an uprising and Cally becomes one of several hostages. She is shot by one of the prisoners when she fights off his attempted rape by biting off his ear.
