A man jumped off a Brooklyn pier and died a short time after emergency responders fished him out of the water, cops said.

The 29-year-old man jumped into the water around 2:30 a.m. near Surf Avenue and West 16th Street early Thursday, according to authorities.

The FDNY Marine Unit responded and was able to fetch him out of the water.

He was transported in critical condition to Coney Island Hospital but later died, cops said.
