The Picton Reading Room and Hornby Library are two grade II* listed buildings on William Brown Street, Liverpool, England, which now form part of the Liverpool Central Library.

It was designed by Cornelius Sherlock, and modelled after the British Museum Reading Room, and was the first electrically lit library in the UK.

It was completed in 1879 formally opened by the Mayor of Liverpool, Sir Thomas Bland Royden.

The front is semicircular with Corinthian columns, and the shape was chosen by the architect to cover the change in the axis of the row of buildings at this point.

It stands behind the older building and the interior is decorated in the Edwardian Imperial style.
