Michael James Breaugh (born September 13 1942) is a former Canadian politician. A teacher by training he was a member of the executive of the Ontario English Catholic Teachers Association when he was first elected to the Ontario legislature in the 1975 Ontario election as the New Democratic Party MPP for Oshawa, Ontario.

When Stephen Lewis stepped down as Ontario NDP leader, Breaugh ran to succeed him but placed third and last in the 1978 NDP leadership convention.

In the late 1980s he often clashed with then Ontario NDP leader Bob Rae criticising his leadership. In 1990, Breaugh decided to leave Queen's Park and ran for a seat in the Canadian House of Commons in a by-election called in Oshawa to fill the vacancy created by the resignation of former federal NDP leader Ed Broadbent.

Breaugh won the by-election, which was held a month before the 1990 Ontario election that brought Rae's NDP to power.

He was defeated in the 1993 Canadian election that reduced the NDP to nine seats.
