2 Haymarket is a listed building in Sheffield City Centre in England.

The building was constructed in 1871 to serve as Sheffield's head post office.^[1] It was originally intended also to house the local branch of the Inland Revenue, but the space was almost immediately found to be inadequate, and within a couple of months of its opening in 1872, the Revenue moved to offices on Norfolk Street.^[2]

The building has two stories and an attic and is in the classical revival style, adopting a form which was already old-fashioned at the time it was built.^[1] In 1879, it was described as "a fairly handsome Doric structure, but inadequate to the requirements of the rapidly increasing postal and telegraphic business of so large a town".^[2] A further section at the rear of the building, facing Commercial Street, was constructed at the same time and in the same style, but is of a single storey, with a basement below.^[1]

In 1910, a new head post office for the city was constructed on Fitzalan Square.^[3] The building was purchased by the Sheffield Stock Exchange, which opened its new site with a grand ceremony in 1911.^[4] The stock exchange operated until 1967, when the creation of British Steel Corporation dramatically reduced its business.^[1][5]

The building was restored in the 1970s, and the interior was completely reworked to serve as a branch of the Yorkshire Bank,^[6] which it remained until September 2014. The building is Grade II listed.^[7]

As of July 2017, the building remains unoccupied following Yorkshire Bank's vacation of the site. There are currently plans for the refurbishment of 2 Haymarket and the adjacent building at 5-7 Commercial Street, which would include the addition of a second floor on the Commercial Street building and the creation of 11 flats across both buildings.^[8]
