The Vale of Glamorgan MP Alun Cairns has kept his job as Welsh Secretary.
Theresa May has been reshuffling her cabinet following a general election campaign which saw her party lose its Commons majority.
Mr Cairns’ re-appointment comes after the party lost three seats in Wales.
During the campaign, he and Welsh Tory leader Andrew RT Davies clashed after both declined to take part in a TV election debate.
Mr Cairns said he was “delighted” to be reappointed.
“I will continue to work closely and constructively with businesses, local authorities, communities as well as the Welsh Government to secure the best possible outcomes for people in Wales,” he said.
The Conservatives, which made a net loss of 13 seats across Great Britain, lost the two seats it gained from Labour in Wales at the 2015 election.
Welsh Tory MPs Guto Bebb and David Jones are waiting to hear if they will continue in their respective Wales Office and Brexit posts.
Meanwhile, Barry-born Damian Green, MP for Ashford, has been promoted to first secretary of state and minister for the cabinet office.
