Harold Bertram Lowes (1 October 1926 – 22 August 2002) was an Australian lawyer and politician.
He was a Liberal Party member of the Legislative Assembly of Queensland from 1974 until 1977, representing the electorate of Brisbane.
Lowes was born in South Brisbane, the grandson of former Speaker of the Legislative Assembly of Queensland William Bertram.
His seat was merged with the adjacent seat of Baroona, held by fellow Liberal Dennis Young, to form Brisbane Central at the 1977 election, and Lowes retired and returned to his legal practice, Phillips & Lowes.
He left his firm to one of his sons, Geoffrey, in 1988, and worked as a legal officer for the Department of Harbours and Marines until 1992.
