Rozanne Foyer (born November 1972) is a Scottish trade union leader.
Foyer grew up in Glasgow, where she helped out on her parents' market stall in the Barras. She left school after her Highers, and worked in the VAT office, but left after being sexually harassed and unsure of her rights, an experience which inspired her to join a union.
Foyer worked for the Benefits Agency, where she led a successful campaign against privatisation. This led the Graphical, Paper and Media Union to take her on full-time as a trainee organiser, following which she became an assistant secretary at the Scottish Trades Union Congress (STUC). Her next appointment was as a national officer for the Transport and General Workers' Union, and after it became part of Unite, she worked in its national organising department.
Foyer served on the general council of the STUC for many years, served a term as chair of the STUC's youth committee. In 2020, she was appointed as General Secretary of the STUC, the first woman to hold the post.
