Jesmyn Ward (born April 1, 1977) is an American novelist and a professor of English at Tulane University, where she holds the Andrew W. Mellon Professorship in the Humanities. She won the 2011 National Book Award for Fiction for her second novel Salvage the Bones, a story about familial love and community in facing Hurricane Katrina. She won the 2017 National Book Award for Fiction for her novel Sing, Unburied, Sing.

She is the only woman and only African American to win the National Book Award for Fiction twice. All of Ward's first three novels are set in the fictitious Mississippi town of Bois Sauvage. In her fourth novel, Let Us Descend, the main character Annis perhaps inhabits an earlier Bois Sauvage when she is taken shackled from the Carolina coast and put to work on a Mississippi sugar plantation near New Orleans.

Jesmyn Ward was born in 1977 in Berkeley, California. When she was three, her parents returned to DeLisle, Mississippi, where they were originally from. She reportedly developed a love-hate relationship with her hometown after having been bullied by classmates both at public school and while attending a private school paid for by her mother's employer.

The first in her family to attend college, Ward earned a Bachelor of Arts in English in 1999, and a Master of Arts in media studies and communication in 2000, both at Stanford University. Ward chose to become a writer to honor the memory of her younger brother, who was killed by a drunk driver in October 2000, just after Ward had completed her master's degree. The driver responsible was not charged for her brother's death, only for leaving the scene of the car accident.

In 2005, Ward earned a Master of Fine Arts in Creative Writing from the University of Michigan. Shortly afterwards, she and her family were impacted by Hurricane Katrina. With their house in DeLisle flooding rapidly, the Ward family set out in their car to get to a local church, but ended up stranded in a field full of tractors. When the owners of the land eventually checked on their possessions, they refused to invite the Wards into their home, claiming they were overcrowded. The family was eventually given shelter by another family down the road.

Ward went on to work at the University of New Orleans, where her daily commute took her through the neighborhoods ravaged by the hurricane. Empathizing with the struggle of the survivors and coming to terms with her own experience during the storm, Ward was unable to write creatively for three years – the time it took her to find a publisher for her first novel, Where the Line Bleeds.

In 2008, just as Ward had decided to give up writing and enroll in a nursing program, Where the Line Bleeds was accepted by Agate Publishing. The novel was picked as a book club selection by Essence magazine and received a Black Caucus of the American Library Association (BCALA) Honor Award in 2009. It was shortlisted for the VCU Cabell First Novelist Award and the Hurston/Wright Legacy Award. Starting on the day twin protagonists Joshua and Christophe DeLisle graduate from high school, Where the Line Bleeds follows the brothers as their choices pull them in opposite directions. Unwilling to leave the small rural town on the Mississippi Coast where they were raised by their loving grandmother, the twins struggle to find work, with Joshua eventually becoming a dock hand and Christophe joining his drug-dealing cousin. In a starred review, Publishers Weekly called Ward "a fresh new voice in American literature" who "unflinchingly describes a world full of despair but not devoid of hope."

From 2008 to 2010, Ward had a Stegner Fellowship at Stanford University. She was the John and Renée Grisham Writer in Residence at the University of Mississippi for the 2010–2011 academic year.
