Ground Zero responders and lower Manhattan residents sickened or injured in the 9/11 attacks can forget about any financial help from Uncle Sam before the holidays.

Nearly two years after President Obama signed the James Zadroga 9/11 Health and Compensation Act on Jan. 2, 2011, no one has gotten a dime.

"We're going into the third year of the law, and the fact that no one's been compensated after eight years of hard work to get the bill passed is unacceptable," fumed Ground Zero advocate John Feal.

Congress appropriated $2.7 billion for a reopened Victim Compensation Fund to dole out $875 million in the first five years and the rest in 2016.

So far, 15,000 firefighters, cops, hardhats and others who lived, worked or went to school downtown have registered as potential claimants. But only 1,500 have filed applications, officials told The Post.

Cancers were recently added to the covered illnesses, but the fund has yet to issue the forms for those applications.
