The answer to this question depends on when it is asked, and can be any of Venus, Earth or Mars.
Mercury is the closest planet to the Sun. Hence its nearest neighbour, in terms of the planets' solar orbits, is Venus (the second planet from the Sun).
Depending on their relative positions on their orbit, however, Venus is not necessarily the closest planet to Mercury.
For example, presently (7 January 2009) the two are fairly close - approximately 64 million kilometres. However, one year from now Venus and Mercury will be on opposite sides of the Sun, about 156 million kilometres apart. Earth, at just over a hundred million, will be much closer to Mercury.
In the same manner, it is also possible (although rarer) for Mars to be closer to Mercury than either Earth or Venus, as will be the case from 21 October-16 November 2010.
The closest star is the Sun and the closest planet is Venus!

Mercury is the closest planet to our sun.
Mercury is closest to the Sun; however, seeing as Pluto is no longer a planet, Mercury is now the smallest planet as well.
The planet which is the nearest to the Sun is Mercury, which also happens to be the smallest planet in our Solar system.
