Welshman Ncube (born 7 July 1961) is a Zimbabwean politician. He is the President of the Movement for Democratic Change – Ncube, and since February 2009 has been the Minister of Industry and Commerce. He was elected as a member of the House of Assembly of Zimbabwe for Bulawayo North East in the 2000 election and served in the House of Assembly until 2008. Ncube is an academic lawyer who has been Professor of Law at the University of Zimbabwe from 1992.

He has a BL (Bachelor of Law) LLB (Bachelor of Laws) and an MPhil (Law) degrees from the University of Zimbabwe. His MPhil thesis was on Zimbabwean Customary Law focusing on Family Law.

In 1997 Ncube bought 30 square kilometres of land with the intention of developing it as a farm but it was seized under the government's land redistribution programme. The land had not previously been farmed. In 2002 Ncube was one of three MDC MPs to be charged with high treason over an alleged plot to assassinate Robert Mugabe, but like the others was found not guilty.

The MDC National Council voted to take part in the elections, MDC leader Tsvangirai tried to expel the selected candidates from the party and suspended Ncube pending disciplinary hearings at the MDC congress in February 2006, but failed because he could not do so constitutionally. The MDC group met in congress in Bulawayo and chose Arthur Mutambara as its new President.

On 16 June 2007, Ncube and Tendai Biti, the Secretary General of the MDC-Tsvangirai faction, met with Justice Minister Patrick Chinamasa and Labor Minister Nicholas Goche, in Pretoria, South Africa. South African President Thabo Mbeki, appointed by the Southern African Development Community, presided over the negotiations, which sought to end economic sanctions on Zimbabwe.

Ncube is instrumental in the talks for the Zimbabwe unity government and is a principal representing the MDC. In 2011 after his party elected him to the presidency, Robert Mugabe refused to swear him in as the Deputy Prime Minister of the state as agreed in the Global Political Agreement. When the ZANU-PF–MDC national unity government was sworn in on 13 February 2009, Ncube became Minister of Industry and Commerce.
