Go West Midlands is a former bus company based in Birmingham in the United Kingdom. It was owned by Go-Ahead Group and was formed through Go-Ahead buying Probus Management Limited (trading as People's Express, and before that Pete's Travel) and Birmingham Coach Company (trading as Diamond Bus) and merging the two. Bus services were operated throughout the West Midlands (region) under the Diamond name. Go West Midlands was seen as the second biggest operator in the West Midlands with National Express West Midlands (Travel West Midlands at the time) being the biggest.
