Vicki Knafo (Hebrew: ויקי קנפו; born 1960) is an Israeli social activist.

She led the 2003 single-mothers struggle against austerity decrees limiting child allotments, a policy initiated by then-finance minister Binyamin Netanyahu as part of a program to cut government spending in the areas of welfare and aid, which was aimed primarily at income support and other programs aimed at marginalized sectors of the population, such as single mothers.

On July 2, 2003, Knafo set out on a march from her home in the southern town of Mitzpe Ramon to the Ministry of Finance in Jerusalem.

[4] Along her way, Knafo garnered support from various social activism and interest groups, among them Ahoti, the Mizrahi feminist movement, New Israel Fund, and more.

[5][6] Several Mizrahi feminist from Ahoti joined specifically to protect Knafo from the police, who tried several times to curtail her march.

Knafo fasted for 18 days, before she agreed to break her strike in the President's residence, at his request, as he voiced support and appreciation for her struggle.
