The Growstown School is a historic one-room school located in the Growstown neighborhood of Brunswick, Maine, United States. Built in 1849, and opened on February 22 of that year, it was saved from demolition in 1971 after local residents intervened, an act that included the installation of a new roof on the property. It was restored over time, including by the American Association of University Women (AAUW) in 1983 and later by the town's public works department. It is now the only remaining one-room schoolhouse in Brunswick of a one-time twenty-six. Betty Fitzjarrald, who chaired the restoration effort for the AAUW, died in 2022, aged 87.
