Either osmium or iridium. There has been contraversy over that as each metal has different crystal structures and each has a different density. They are each very close to another in density so the official disclosure on which is heavier has actually changed several times.
by the way
iron is 7.87g/cm3
lead is 11.3 g/cm3
gold is 19.3g/cm3
iridium and osmium are both 22.6g/cm3
uranuim is 19g/cm3
and theres no density information available on anything past actinum because of the difficulty in obtaining a weighable amount that actually doesnt decay in the time it takes to weigh it.

Ok, here's the first good answer. And I'll tie together all the other answers that have been given.
It depends how much of it you have. 5 pounds of aluminum is heavier than 2 pounds of lead, or osmium, or uranium, or anything else.
If you are looking for the DENSEST metal, the answer is either osmium or iridium.
If you are looking for the metal with the heaviest atomic mass, then the answer is ununhexium.
If you are looking for the naturally occurring metal with the heaviest atomic mass, then the answer is uranium.
If you are looking for a nonradioactive metal with the heaviest atomic mass, then the answer is lead.

Janno,
The answer to your question is Osmium, which has a density of about 22.6 g/mL, heavier than any other known metal. It is true that Iridium has a density that is very close, but most determinations show osmium's density to be slightly higher. Those who answered uranium and unnunhexium are going by atomic number, which does not necessarily correlate directly with density, which is what I assume you mean by "heaviest". Those who answered lead are probably just going with the heaviest metal that they are familiar with, but if you look this up you will find that osmium is much heavier.

The heaviest metal is Osmium, with a specific gravity of 22.48. Iridium is sometimes stated as being as heavy, or heavier, with a specific gravity of 22.4.
These metals are very similar to platinum, which is slightly less dense at 21.46.
Gold is also very heavy, with a specific gravity of ab bout 20. By comparison, iron has a specific gravity of about 7.

Uranium is the heaviest metal that occurs in nature.

Osmium is a hard metallic element which has the greatest density of all known elements. It is twice as heavy as lead, and has a specific gravity of 22.59. (The specific gravity of lead is 11.35; gold is 19.32; and platinum is 21.45.)
Osmium has an atomic weight of 190.2 and its atomic number is 76.
