Nokia 5800 XpressMusic is a Symbian smartphone from Nokia as part of the XpressMusic line. It was unveiled on 2 October 2008 in London and started shipping in November of that year, marking the company's first mainstream phone with a touchscreen. The Nokia 5800 was the first device to run S60 5th Edition (later referred to as Symbian^1), designed as a touch-specific version of the S60 platform which was otherwise originally built for use using a traditional D-pad and keypad.

Positioned as a mid-range offering, Nokia 5800 XpressMusic has a 3.2-inch display with a resolution of 640x360 pixels. The 16:9 aspect ratio display was the first among mobile phones. The resistive touchscreen features tactile feedback, though it does not use Nokia's Haptikos technology. While rich in multimedia, it also had many features standard to the flagship Nokia Nseries, such as GPS, HSDPA and Wi-Fi support. The S60 5th Edition interface has a compatibility mode for S60 3rd Edition software as well as Java applications, that are not touchscreen-aware, using virtual keys on-screen.

Code-named "Tube", it was a highly anticipated device in 2008 and went on to become a commercial success with 8 million units sold a year after release, becoming the firm's first major smartphone hit in almost two years since the Nokia N95 debuted. The Nokia 5800 was praised for its supplied stylus and affordability, but was viewed negatively by critics for its camera and software issues. Nokia supported the 5800 with firmware updates until 2011.

The Nokia 5800 XpressMusic is not the first touchscreen device in Nokia's range of handsets. In 2004, the Nokia 7700 was announced, a Series 90 Symbian device that was cancelled before it reached the market. This was followed by the Nokia 7710 which was an upgraded version of the 7700 and became available during 2005. Nokia also produced the UIQ-based Nokia 6708 phone in 2005, but this was not an in-house development and was bought in from Taiwanese manufacturer BenQ, and it targeted the Chinese market. Nokia have also produced a range of Maemo-based tablets called the Nokia Internet tablet range, which have a touchscreen interface but are not mobile phones by themselves. The 5800 is, however, Nokia's first S60-based Symbian touchscreen device and hence their first mainstream touchscreen handset. Public interest in touchscreen mobile phones rose significantly in 2007 after Apple released the iPhone. Nokia's rivals LG and Samsung had both also launched consumer-oriented touchscreen handsets during this time.

At Nokia's Go Play event in London on 27 August 2007 — where the Nokia N81, N81 8GB, Nokia N95 8GB, Ovi, Nokia Music Store and N-Gage 2.0 were unveiled, — the company's CEO Olli-Pekka Kallasvuo also said that a touchscreen-operated smartphone based on the S60 platform will be launched in the following year. The event also showcased a touch-operated concept running S60 software. The device presented in the video was remarkably iPhone-like, which Engadget referred to as the "Nokia iPhone". It was later explained that the concept was regarding the touch software and not the hardware device mock-up.

At the Symbian Smartphone Show in October 2007, Nokia announced and showed an S60 touch interface, stating that it will be released in 2008. It was demoed during the 2008 Mobile World Congress. Many rumours started circling around regarding Nokia's first touchscreen S60 smartphone. On 8 April 2008, images of this device and running an early touch-based interface were leaked and soon a Nokia official confirmed that the company is working on such a device, codenamed "Tube". Nokia soon also bought out Symbian Software and made the operating system open source with its partners under the Symbian Foundation. This also led to S60 being adopted as the sole user interface and the discontinuation of UIQ.

The "Tube" was widely leaked and discussed about during the year. Notably a prototype of the Tube also appeared in The Dark Knight, released in cinemas in July 2008. The scene where this prototype appears was during the final scenes which were shot in Hong Kong in November 2007.

Nokia unveiled the "Tube" 5800 XpressMusic at the Remix event held at Koko in London on 2 October 2008. Alongside the handset, the company also announced the Comes With Music service and a number of stereo wireless Bluetooth headphones. The device began shipping on 27 November 2008 retailing for €279 before taxes and initially available in markets including Finland, Spain, Russia, India and Hong Kong. It launched in other territories in 2009, including in North America in March 2009. Nokia also expanded the Nokia Music Store availability globally to complement the release of the 5800.
