A tourist was repeatedly stabbed by a crazed homeless woman inside Macy’s Herald Square Thursday afternoon amid the packed holiday shopping rush, according to cops and law enforcement sources.

The 38-year-old California victim, who was shopping with her husband during the Big Apple’s crowded holiday season, was knifed in the back, shoulder, and arm in the seventh-floor bathroom of the flagship store in Midtown at 3:13 p.m., police and sources said.

The victim suffered multiple stab wounds to her back and a laceration on her right arm, cops said.

The victim, visiting from Jurupa Valley, works as a civilian for the state’s sheriff’s office, where her husband serves as a sheriff, sources said.

A female person of interest has since been taken into custody, according to police.
