Sir James O'Grady, KCMG (6 May 1866 – 10 December 1934) was a trade unionist and Labour Party politician in the United Kingdom. He was the first colonial governor appointed by the Labour Party from within its own ranks.
O'Grady was re-elected at the elections in January 1910 and December 1910 elections, and when the Leeds East constituency was abolished for the 1918 general election, he was returned unopposed for the new Leeds South East constituency. He held that that seat until he stepped down from Parliament at the 1924 general election.
In the House of Commons, he spoke frequently, particularly on foreign affairs, and was noted as a strong supporter of the First World War, speaking at recruitment rallies. He was also Labour's only Roman Catholic MP.
Through his role in the Amalgamated Union of Cabinet Makers, he had been President of the Trades Union Congress in 1898, and he continued his union activities whilst an MP. After a variety of posts in unions related to the furniture trades, he became general secretary of the National Federation of General Workers in 1918.
Instead he became Governor of Tasmania from 1924 to 1930. The first Labour politician to be appointed as a colonial governor by a Labour government, his appointment was resisted by the Australian Labor Party, which wanted the job to go to an Australian.
He was knighted with a KCMG and moved to Tasmania, taking office on 23 December. His governorship was marked by conflicts with the Legislative Council (which urged to do more to promote economic development), and his governors reports were outspoken, but he appears to have parted on good terms.
His next appointment was in 1931, as Governor of the Falkland Islands, but he retired in 1934 due to ill-health. He died later that year, aged 68.
