Hove Library is a public lending library serving Hove, part of the English city of Brighton and Hove. The "highly inventive" Edwardian Baroque/Renaissance Revival-style building, a Carnegie library designed by the architects Percy Robinson and W. Alban Jones of Leeds, opened in 1908 on Church Road, succeeding a library founded in 1890 in a house on the nearby Grand Avenue. The building has been listed at Grade II by Historic England for its architectural and historical importance.

Hove, immediately west of the fashionable resort of Brighton, grew rapidly during the Victorian era: there were a few hundred residents in the 1830s, about 9,000 by 1861, and more than 36,000 by 1901. It became an urban district in 1894 and was incorporated as a municipal borough four years later. Rapid housing development was matched by a generous provision of public buildings: schools, dispensaries, hospitals, churches and a town hall. In April 1890 the forerunner of Hove Borough Council, the Hove Commissioners, set up a committee to investigate how to establish a free library in Hove. Their view was that premises should be rented, as constructing a purpose-built library would be too expensive. The requirements of the Public Libraries Act meant residents had to vote on "the desirability of establishing a public library", and a ballot took place in late March 1891. A majority of residents were in favour.

By November 1891 the commissioners had put aside £500 for the scheme, and William Willett was offering to rent the house at 11 Grand Avenue for £100 per year, rising to £150 in the third year. The £500 would not cover purchasing books, so the commissioners asked wealthy residents to donate material. By the following month there was enough stock for the library to be opened, initially as a reading room only and with a caretaker rather than a full-time librarian (one was appointed in January 1892 though). Lending facilities began on 24 October 1892. As well as a wide range of books and periodicals, such as complete sets of Punch, the Encyclopædia Britannica and the Imperial Gazetteer of England and Wales, collectors of curiosities and artworks such as Constantine Alexander Ionides had lent or donated various items such as reproductions of works by Michelangelo and Raphael, a disembowelling knife, a Japanese executioner's sword and a set of assegai spears.

The library was immediately popular: by 1893 there were nearly 600 members, a reference library was created in January 1894, and the opening hours were extended to 11 hours per day with half-day closing on Fridays. By 1900 the hired premises were no longer suitable because of overcrowding and the sheer weight of books, and the borough council formed a committee to investigate whether a permanent library should be built. In the interim, a larger building was hired at 22 Third Avenue, and Hove Library moved there from 23 June 1901.

The library committee—apparently without the knowledge of the wider borough council—approached Andrew Carnegie, who was known for funding many libraries in Britain and abroad, for assistance in 1903. Carnegie agreed to donate £10,000 towards a permanent library building if a site could be found and purchased without a surcharge on the rates and subject to the principles of the Free Public Libraries Act. The site of a council depot on the south side of Church Road, already owned by the council but not yet fully paid for, was identified in that year, and after some difficulties it was chosen in March 1905. The depot was demolished later that year, and an architectural competition was held to find a suitable design for the library. Of the 71 entries, ten were shortlisted and were scrutinised by RIBA president John Belcher. The design submitted by Percy Robinson and W. Alban Jones of Leeds was the winner, and the plans were signed off by the council in October 1906.

After initial works started in February 1907, the foundation stone was laid on 10 June 1907 by the Mayor of Hove, Alderman Bruce Morison. F.G. Minter was the building contractor, having offered the cheapest bid (£9,999) during the tendering process; overall, construction cost £13,500. The new library was opened by Margaret Child Villiers, Countess of Jersey, on 8 July 1908. The two-storey building had a roof garden on the upper floor, to which a glazed screen was added c. 1913. A juvenile library was added in 1920 by converting the basement, and by that year nine staff were employed. Meanwhile, wealthy residents continued to donate thousands of volumes—including many rarities—to the library, along with various artworks and curiosities (all of which were moved to the new Hove Museum at nearby Brooker Hall when that opened in 1927).

The old roof garden was replaced in 1925 by the Wolseley Room, named in memory of Field Marshal Garnet Wolseley, 1st Viscount Wolseley and paid for by his daughter Frances Garnet Wolseley, 2nd Viscountess Wolseley. It was used both for the display of artworks and as a storage and viewing facility for deeds and manorial rolls relating to Sussex parishes. These have been moved to other facilities, but there is still a repository of Wolseley family papers. Money was left to Hove Borough Council to maintain the facility, and the room was refurbished in 1970.

Abortive plans in the 1960s included an eastward extension of the library building (a project curtailed by the destruction of Hove Town Hall in a fire in 1966 and the need to rebuild it) and the opening of a branch library near St Thomas the Apostle's Church in the north of Hove. In December 1983, the contents of Hove's separate music library were integrated into the main library. Hove Music Library had opened a short distance along Church Road from the main library in March 1966. Major refurbishment work was carried out in 1988–89, and the library was awarded Grade II listed status on 2 November 1992.
