Jacqueline MacInnes Wood (born 17 April 1987) is a Canadian actress, disc jockey, singer and television host. She is best known for starring as Olivia Castle in the horror film Final Destination 5 (2011) and as Steffy Forrester in CBS soap opera The Bold and the Beautiful (2008-present), the latter earning her four Daytime Emmy Award nominations, winning Outstanding Lead Actress in a Drama Series in 2019.

Jacqueline MacInnes Wood was born in Windsor, Ontario, the daughter of (Sandie) Alexandra MacInnes and James C. Wood. She is of indigenous (Cree), Scottish, French and Brazilian ancestry. Her half sister is Dani Probert, who was the wife of the late NHL player, Bob Probert. Her great uncle was Scottish highland singer Alasdair Gillies. Wood took acting classes at Ryerson University, Centre for the Arts and the Armstrong Acting Studio.

In 2012, Wood received her first nomination for Outstanding Younger Actress in a Drama Series for her portrayal of Steffy at the 39th Daytime Emmy Awards. Of learning about her Emmy nomination, she said, "I was just about to shoot a scene in the Adriatic sea in Italy. The water was only 54 degrees! [Executive Producer/Head Writer] Brad Bell came up to me and said, "How does it feel to be Emmy nominated?" For that year, Wood submitted the scenes in which Steffy is informed of the end of her affair with Bill. In 2013, Wood garnered her second consecutive nomination in that category at the 40th Daytime Emmy Awards, in which she submitted the scenes where Steffy surprises Liam (Scott Clifton) by presenting him with signed annulment papers. In May 2013, news broke that Wood had opted not to renew her contract with the show in order to take another break. A representative for the show stated: "[Wood] is taking short a break, as she has done in the past, from B&B. She remains as the character of 'Steffy Forrester' and is continuing to tape, with episodes airing through July 2013 and then beyond". It was later announced that Wood has decided to remain with the series on a recurring basis. In April 2015, it was announced that Wood would reprise her role on B&B on a contract basis, which she has remained on ever since.

In 2011, she starred in her first feature film, Final Destination 5. In September 2010, Wood's casting was announced and it was revealed that filming was underway in Vancouver, British Columbia, Canada. This film is the fifth in the Final Destination horror film franchise. Wood portrayed Olivia Castle. The character was described as "a smart mouthed beauty who wears glasses" and is "caught in a spine chilling, stomach churning situation that will make viewers squirm in their seats", which was a risky eye procedure which Wood was terrified to do. Final Destination 5 was a critical and commercial success, grossing over $157 million at the American Box Office, and becoming the highest-rated film from the franchise at the website Rotten Tomatoes, where it has been awarded a "Fresh" rating, consisting of 61% positive reviews from film critics. Her performance also received very positive reviews.
