India B. Walton (née Suttles; born June 14, 1982) is an American political activist and nurse. In 2021, she defeated incumbent Byron Brown in the Democratic Party primary for mayor of Buffalo, New York, before losing to Brown in the general election, where he ran as a write-in candidate.

Walton was born on the east side of Buffalo, New York to Doris Siddiq and Louis Kelly. She was raised by her mother, who was a pharmacy technician, with five siblings. She attended Lorraine Elementary and Leonardo da Vinci High School. Walton gave birth to her first child when she was fourteen, dropped out of high school, worked at Family Dollar and McDonald's, and lived in a group home for young mothers. She married Vernon Walton Jr. and left high school after giving birth to twin sons at the age of nineteen. Walton later earned a General Educational Development certificate and graduated with a nursing degree from SUNY Erie. She has said she decided to pursue a career in nursing after her experience following the birth of her twins, who were born premature and required months of intensive care. She later gave birth to another son.

After she completed her nursing degree, she began work at Children's Hospital. In 2014, she was arrested on a charge of harassment, and the case was dismissed by the court. In 2014, she also moved out of her home due to what she has described as abuse and physical violence by her husband, and later divorced her husband after an attempt to reconcile in 2015 was unsuccessful.

Walton became active in politics at the age of twelve when she protested Rockefeller Drug Laws with her mother as part of the activist group Families Against Mandatory Minimums. While working as a nurse, she served as a representative for 1199SEIU United Healthcare Workers East. In 2016, after participating in meetings held by the Community First Alliance, a local organization focused on advocacy for residents in the majority-Black Fruit Belt neighborhood, she held a protest against parking practices in the neighborhood. She left her nursing career after being hired by Open Buffalo as a community organizer with a focus on criminal justice and policing reforms. In 2017, she became executive director of Fruit Belt Community Land Trust.

She was also a leader in local Black Lives Matter protests, and advocated for Mayor Byron Brown to sign Cariol's Law. She has said the shoving of Martin Gugino by a Buffalo police officer was one of her inspirations to run for political office.

Walton announced her campaign for the mayoralty of Buffalo in the 2021 election on December 13, 2020. During the primary campaign, Byron Brown, who had served as mayor for four terms, refused to debate Walton. The Working Families Party endorsed and supported Walton during her campaign, after having previously endorsed Brown in his past campaigns. She was also endorsed by the Democratic Socialists of America and the Buffalo Teachers Federation, a union with 3800 members. Walton defeated Brown and Le'Candice Durham in the primary election on June 22, 2021, 52 to 45 percent. After her primary win, The Buffalo News reported, "observers saw Walton's win as yet another signal that a dynamic candidate can knock off a complacent incumbent anytime, anywhere – which might just encourage more challengers to take on long-serving elected officials elsewhere in New York and beyond."

During the course of her campaign, Walton was endorsed by Senate Majority Leader Chuck Schumer, Senator Kirsten Gillibrand, and New York City public advocate Jumaane Williams, and supported by Senator Bernie Sanders, Senator Elizabeth Warren, and Representative Alexandria Ocasio-Cortez. She was also endorsed by the Erie County Democratic Committee. Her campaign raised $150,000 compared to Brown, who raised over $500,000 and received support from the Police Benevolent Association and Republicans. On October 23, 2021, CNN reported the mayoral election "escalated over the summer and into the fall as a proxy fight between the city and state's growing progressive movement and more business-friendly, establishment Democrats determined to block Walton's ascent".

Walton is a democratic socialist, and a member of the Democratic Socialists of America. In an interview with Rolling Stone, published in July 2021, she stated, "It's my responsibility to explain to folks that being a democratic socialist does not mean that I'm interested in seizing people’s private property." During a mayoral election debate in late October 2021, in response to Brown stating, "I don't see Ms. Walton as a Democrat," she replied, "I won the Democratic primary. Secondly, I am a self-avowed democratic socialist. The first word in that is 'Democrat.'"
