Megan McTavish (born 1949) is an American soap opera writer, most known for her head writing stints on All My Children. Before writing, however, she played Lola Fontaine on Guiding Light from 1983 to 1984.

Starting as a team writer in 1987, she helmed All My Children from 1992 to 1995 and from 1997 to 1999. Her first stint was critically lauded, using characters and past plot points that hearkened back to the show's golden era in the 1970s and 1980s. Her writing style helped the show keep its #2 spot in the Nielsen ratings that it had held in the 1980s under the tenure of Wisner Washam. She left the show after three years to write Guiding Light from 1995 to 1997.

Her second stint, fresh from her stay at Guiding Light, was, for the most part, not well-received. She then left AMC for One Life to Live, which she wrote from 1999 to 2001.

After a short-lived tenure at General Hospital, she returned to All My Children in 2003, where she is today.
