The Allegheny Front is an award-winning public radio program covering environmental issues in Western Pennsylvania, airing on WESA in Pittsburgh and on stations throughout the region.

The Allegheny Front began in 1991 on WYEP 91.3 FM as a new urban environmental consciousness was strengthening in Pittsburgh. As originally created by volunteer Lucy Laffitte, who coined the name after the major escarpment in the Allegheny Mountains east of Pittsburgh, the program provided environmental news, events and interviews with people active in the local environmental community.
