Symphony No. 88 in G major (Hoboken I/88) was written by Joseph Haydn, for the orchestra of Esterháza under the benevolent Prince Nikolaus Esterhazy. It is notably the first of his symphonies written after the completion of the six Paris symphonies in 1786.
The symphony was completed in 1787, just like his 89th symphony. It is one of Haydn's best-known works, even though it is not one of the Paris or London symphonies and does not have a descriptive nickname. It is sometimes referred to as The Letter V referring to an older method of cataloging Haydn's symphonic output.
