Sienna Blake (also Bradley) is a fictional character from the British Channel 4 soap opera Hollyoaks, played by Anna Passey. The character made her first appearance on 21 November 2012 and was introduced as the estranged twin sister of established character Dodger Savage (Danny Mac), along with her father Patrick Blake (Jeremy Sheffield). Emily Lawrance was originally selected for the role, however Passey replaced her within weeks and only she has appeared on-screen as Sienna. The character has had a daughter, Nico (Persephone Swales-Dawson), with Dodger, and twins Sebastian and Sophie with Warren Fox (Jamie Lomas), an affair with Darren Osborne (Ashley Taylor Dawson), a marriage with Ben Bradley (Ben Richards), an affair with Trevor Royle (Greg Wood) who was later killed by Nico, a relationship with her half-sister Liberty Savage's (Jessamy Stoddart) former boyfriend Brody Hudson (Adam Woodward), and been diagnosed with cervical cancer while pregnant. Passey took a short break from the show in early 2020 and was absent between 17 January and 30 March.

In February 2024, Sienna discovers that her love rival Dilly Harcourt (Emma Johnsey-Smith) is Patrick's daughter and her half-sister. However, in the episode aired on 21 August 2024, it was revealed that Patrick was not Sienna's father; it was, in fact, his twin brother Jeremy Blake (also played by Sheffield). Sienna enters into a relationship with Ethan Williams (Matthew James-Bailey), but accidentally pushes him to his death on their wedding day, when his affair with Vicky Grant (Anya Lawrence) is revealed. Jeremy helps her conceal Ethan's murder, and he frames Dilly; Sienna discovers later that Jeremy had killed her and is a serial killer. On 22 October 2025 Sienna is one of many Hollyoaks characters that appears in the crossover with Brookside.
