Not according to the current definitions of "planet" or "dwarf planet".
However, as research on extrasolar planets progresses, I think another revision of the definition to include companions of certain sub-stellar objects - namely brown dwarfs - might occur.
It's highly doubtful that any of the moons in our solar system will ever be considered "planets" by any definition, though more precise definitions of groups of planetary companion objects including a group of planet-like companions to gas giants may well become necessary.

The Earth's Moon is the most popular satellite in the universe. It's diameter is over one-fourth that of the Earth. Gravity on the Moon is not sufficient to maintain an atmosphere. The Moon and the Earth revolve around their mutual center of gravity as a sort of "double planet." The Moon orbits the Earth and rotates on its axis at the same rate as the Earth. Therefore, we only see one side of the Moon and must depend on transmissions from space vehicles for images of the far side. The far side is also densely cratered.
The moon is a planet

The moon is a satellite of the earth, but it some ways behaves more like a planet of the solar system. It is highly inclined to the earth's equator and follows a path closely resembling the planets on the ecliptic. The moon's path through the heavens allegedly gave Isaac Newton a headache!

no! i don't think so!
A planet has a strict definition in astronomical terms. In the solar system, a planet must be in orbit around the sun. The moon however, is in orbit around the earth. Therefore it is not classed a planet.
The definition of planet has been controversial lately, following the declassification of Pluto from planet to dwarf planet.

If you think of a planet as a smaller body that revolves around a larger body, then the moon is a planet of the Earth.
Northstar and doug are right - I was just saying how you could consider it a planet.

no, a moon is not a sort of planet. a moon is a natural sattelite. our moon happens to be made from earth rock and another planets rocks. a planet orbits a star directly, and has to have a couple more qualifiacations.

No. Planets orbit around a star. Moons orbit around a planet.

No, by definition.
A planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, not massive enough to cause thermonuclear fusion in its core, and has cleared its neighbouring region of planetesimals.
The short answer is No.

No. Planets orbit a star directly, but moons orbit a secondary body directly, not a star.

Actually moon is not a planet....
