The Symphony No. 5 in C minor, Op. 67, also known as the Fate Symphony, is a symphony composed by Ludwig van Beethoven between 1804 and 1808. It is one of the best-known compositions in classical music and one of the most frequently played symphonies, and it is widely considered one of the cornerstones of western music. First performed in Vienna's Theater an der Wien in 1808, the work achieved its prodigious reputation soon afterward. E. T. A. Hoffmann described the symphony as "one of the most important works of the time". As is typical of symphonies during the Classical period, Beethoven's Fifth Symphony has four movements.

A symphony is an extended musical composition in Western classical music, most often for orchestra. Although the term has had many meanings from its origins in the ancient Greek era, by the late 18th century the word had taken on the meaning common today: a work usually consisting of multiple distinct sections or movements, often four, with the first movement in sonata form. Symphonies are almost always scored for an orchestra consisting of a string section, brass, woodwind, and percussion instruments which altogether number about 30 to 100 musicians. Symphonies are notated in a musical score, which contains all the instrument parts. Orchestral musicians play from parts which contain just the notated music for their own instrument. Some symphonies also contain vocal parts.
