The Symphony No. 97 in C major, Hoboken I/97, is the fifth of the twelve London symphonies (numbers 93-104) written by Joseph Haydn. It was completed in 1792 as part of the set of symphonies composed on his first trip to London. It was first performed at the Hanover Square Rooms in London on 3 or 4 May 1792. First published in England, it made its way to the continent a few years later and was used by Ludwig van Beethoven as a model for a symphony in C major he never completed, and by Friedrich Witt for the Jena Symphony.
