Evan Roderic Bowen QC (6 August 1913 – 18 July 2001)[1][2] was a Welsh lawyer and Liberal Party politician.

He failed to succeed Clement Davies as leader of the Liberal Party in 1956 when Jo Grimond was chosen.

His legal work in south Wales resulted in very infrequent appearances in the constituency and his attendance and voting record at Westminster was sporadic.

After the 1964 election when Labour's majority in the House of Commons was just four seats, he was persuaded by the Government to accept the position of Deputy Speaker.

He served as National Insurance Commissioner for Wales, 1967–86, and as president of St Davids University College, Lampeter, 1977–92.
