Mick Ralphs (born Michael Geoffrey Ralphs, 31 March 1944, Stoke Lacy, Hereford, Herefordshire) is an English guitarist and songwriter, who was a founding member of 1970s music bands, Mott the Hoople and Bad Company.

Ralphs played with a blues-rock group called the Buddies (who released a single in 1964) in his teens.

Then a guitarist with the Doc Thomas Group between 1966 and 1968, Ralphs joined Mott the Hoople the following year. In 1973, dissatisfied with Ian Hunter`s growing domination, Ralphs left Mott the Hoople to team up with former Free vocalist Paul Rodgers to form Bad Company. This band ultimately had greater commercial success than Mott The Hoople. Ralphs` composition "Can`t Get Enough", which Mott was unable to record because of the vocal register in which it was written, became an immediate hit and pushed the group`s 1974 debut album to number one in the U.S. Ralphs continued to record and tour with Bad Company until they folded in 1982, when Rodgers announced he was leaving the band (reportedly, a physical confrontation ensued, with self-confessed `wimp` Ralphs taking on Rodgers, who has a black belt in martial arts).

In 1984, he toured with Pink Floyd guitarist David Gilmour on Gilmour`s About Face tour. Ralph`s 1985 solo album, Take This, featured bassist Micky Feat and his fellow Bad Company member, drummer Simon Kirke. Ralphs only managed four gigs in support of the album, but his live band consisted of guitarist Dave Colwell (later to join Ralphs in a reformed Bad Company), Uriah Heep drummer Chris Slade and Ozzy Osbourne keyboard player Lindsay Bridgewater. Prior to rejuvenating Bad Company Ralphs joined Cold Turkey, an act that lasted just one gig.

Bad Company reformed and split several times through the 1980s and 1990s, but Ralphs finally quit for good in 2000. He then announced that he was giving up touring, something he was never comfortable with in either band, since he has a morbid fear of flying.

In 2001, Ralphs released his second solo album, the all instrumental effort It`s All Good, on the Angel Air Records label. Two years later his That`s Life - Can`t Get Enough album was released, including a demo version of "Can`t Get Enough".

In 2004, he once again teamed up with former Mott colleague Ian Hunter, playing second lead guitar (along with Andy York) on Hunter`s UK tour. Ralphs performed at Hunter`s 2005 concert at the London Astoria, with Ralphs performing a guitar solo to "All the Way from Memphis".

On 2 July 2008, it was announced that the original line-up of Bad Company (minus Boz Burrell who died in September 2006) would do a one-off gig at the Seminole Hard Rock Hotel and Casino in Hollywood, Florida on 8 August 2008.[5] According to Paul Rodgers, they did this gig in order to `protect the legacy they have built and cement the rights to the trademark Bad Company for touring`. The now regular line-up of Bad Company which includes Ralphs, along Colwell, Robert Hart, Jaz Lochrie and Gary `Harry` James, played a short UK tour.

On 16 January 2009, it was announced that Mott the Hoople, including Ralphs, would be re-uniting for two concerts at the Hammersmith Apollo in London, on 2 and 3 October 2009. According to Ian Hunter`s website, all five of the original members will participate in the reunion.
