This is subjective and a matter of opinion as there are many famous pieces by Beethoven. Much of his music is recognisable by melody, even though people may not be familiar with the name.
Among Beethoven's piano sonatas, one would consider the Pathétique, Moonlight, Waldstein and Appassionata to be the most famous.
Beethoven's 9 symphonies are all brilliant, but perhaps the better known ones are the "Eroica" (his third symphony), the rich and penetrating Fifth Symphony (Symphony No. 5 in C minor), and the Ninth Symphony (Symphony No. 9 in D minor) which, unlike preceding symphonies, actually made use of choral parts in the well-known "Ode to Joy".
Beethoven also wrote a short, romantic composition, the Bagatelle in A minor, that became known as "Für Elise". It was written in April 1810 for Therese Malfatti, whom Beethoven was considering marrying at that time - a marriage which never eventuated.
Equally famous are his one and only Opera, 'Fidelio' and the 'Archduke Trio', or Piano Trio no.7.
There are far too many exceptional pieces by Beethoven to be able to say which is the "best".
For some, Beethoven's most famous piece of music is the fourth movement of the Ninth Symphony. The reasoning behind this answer is its popularity in the movie industry in addition to its inclusion on scores of hymnals as the tune paired with the text "Joyful, Joyful, We Adore Thee." It is widely regarded as the finest symphonic composition of all time, and Beethoven was completely deaf when he wrote it.
