A woman tried to kidnap a 4-year-old boy outside a Brooklyn McDonald’s — and now cops are asking the public’s help tracking her down.

The little boy was standing with his grandmother outside of the fast food restaurant on Eastern Parkway near Utica Ave. in Crown Heights when the stranger snatched him away and tried to drag him across the street about 5 p.m. Monday, police said.

Another family member stopped the woman from taking the boy and the woman ran off south on Utica Ave. She has not been caught.
