Douglas Nicholls (born 1955 or 1956) is a British trade union leader.
Nicholls was a part-time youth worker in Oxford in 1975, when he joined the Community and Youth Workers' Union (CYWU). In 1982, he moved to Coventry to work full-time in the field, and in 1987 he was elected as general secretary of the CYWU.
In 2007, Nicholls took the CYWU into a merger with the Transport and General Workers Union (TGWU); a few months later, the TGWU became part of Unite the Union, and Nicholls served as a national secretary of Unite until 2011.
