Sara Lance, also known by her alter ego White Canary, is a fictional character in The CW's Arrowverse franchise, first introduced in the 2012 pilot episode of the television series Arrow, and later starring in Legends of Tomorrow. The character is an original character to the television series, created by Greg Berlanti, Marc Guggenheim and Andrew Kreisberg, but incorporates character and plot elements of the DC Comics character Black Canary. Sara was portrayed by Jacqueline MacInnes Wood in the pilot episode, with Caity Lotz replacing Wood in subsequent appearances.

Sara initially goes by the moniker of The Canary, a translation of her Arabic League of Assassins name الطائر الصافر (Ta-er al-Sahfer). She later adopts the code name of White Canary before joining the Legends of Tomorrow, and eventually becoming the captain of the team.

Lotz has appeared as Sara Lance and her superhero persona in crossovers on The Flash, Supergirl and Batwoman, all set within the Arrowverse. The character has also appeared in a digital comic book series.

Sara Lance first appears in the pilot episode of Arrow as the younger sister of Laurel Lance. Five years prior to the beginning of the series, she was having a secret affair with her sister's boyfriend Oliver Queen and was with him on his family yacht when it shipwrecked. Everyone on board was presumed dead but flashbacks in season two reveal that, like Oliver, Sara actually survived the experience. She was rescued by a research boat, the Amazo, and when Oliver was captured by the ship's crew, Sara helped him escape. Together, along with Oliver's friend Slade Wilson, they attacked the ship. Due to Slade's love for Shado, an ally who was killed indirectly because of Oliver who was being forced to choose who to live between Sara and Shado, Slade betrayed Oliver and took the ship and Oliver as his prisoner. Oliver and Sara confronted him on the freighter and Sara was swept away in the current, causing Oliver to believe that she died once again. However, Sara was found by Nyssa al Ghul, who took her to Nanda Parbat. She and Nyssa became lovers, and Sara became a deadly fighter with the League of Assassins under the name Ta-er al-Sahfer, roughly translated to "Yellow Bird" or "Canary" from Arabic.

In season two, Sara returns to Starling City after a six-year absence as "The Canary" to protect her family. In keeping with a promise, she also befriends wayward teenager Sin and watches over her. Oliver manages to capture and unmask the Canary, revealing Sara to be alive. She eventually informs her father, SCPD Detective Quentin Lance, and looks after him and Laurel (who also later discovers she's alive and is a vigilante). Sara joins Team Arrow and revisits a brief relationship with Oliver. She aids him and his colleagues Felicity Smoak, John Diggle, and Roy Harper in taking down a drug-enhanced Slade Wilson, with help from the League of Assassins, which requires Sara to return to Nanda Parbat.

In season three, Sara is killed on a rooftop with three arrows to the chest. Some time later, it is revealed that Thea Queen killed Sara after being drugged by her father Malcolm Merlyn as part of a plot to pit Oliver against Ra's al Ghul. Meanwhile, Laurel takes up Sara's mantle to fight crime as the Black Canary.

In season four, Laurel resurrects Sara using the League's mystical Lazarus Pit. The process is successful, but Sara loses her soul, making her feral and dangerous. Oliver calls his old friend John Constantine to assist them in restoring Sara's soul. Days later, Sara aids in rescuing Ray Palmer/The Atom from the hands of Damien Darhk, before leaving town to find herself, eventually joining the Legends along with Ray. During her time away with the Legends, Laurel is killed by Darhk and Sara is later made aware of it by Quentin when she briefly returns to present-day Star City at the end of season one of Legends of Tomorrow, where she and Quentin mourn Laurel together.

Sara briefly returns in season six when she receives a call from her sister's doppelgänger, the recently reformed criminal from Earth-2 Laurel Lance / Black Siren, who informs her that Quentin had been seriously injured in the battle against Ricardo Diaz and is in the hospital. Sara arrives and meets her deceased sister's doppelgänger, who had developed a genuine father-daughter relationship with Quentin; they refer to each other as such. Sara thanks Earth-2 Laurel for calling her; Laurel thanks her for coming. Laurel tells her that the doctors are optimistic that Quentin will make it and asks Sara if it is weird seeing her. Sara replies that it is, a little. Sara asks if she is like her Laurel, and Laurel replies that she hardly is at all, clearly disappointed with herself. The two witness Oliver being arrested for being the Green Arrow per the condition of his agreement with the FBI, in exchange for their help in the fight against Diaz and his allies. The doctor comes and informs everyone present that Quentin has died from lack of oxygen to his brain during surgery, leaving Sara, Laurel, Oliver, and the rest of Team Arrow devastated. Later, as Oliver (under the direction of the FBI) announces to the world on live TV that he is the Green Arrow, before being taken to prison, Sara and Laurel mourn together over Quentin's body.
