Gertrudes Labaça, also called Dona Gertrudes, is a comic character created and performed by Bruno Costa, a hairdresser from Furnas on São Miguel in the Azores, Portugal. She first appeared during the 2020 COVID-19 lockdown as a bawdy, provocative woman who went live on Facebook, and she spread through the local group Vamos Rir Furnas.

She is known for frank, satirical humour about the everyday life of women, including ordinary conversations and the pressure around appearance, body and beauty standards. Her speech uses typical São Miguel expressions and an unfiltered, irreverent tone. A TVI report in 2021 and a guest spot on RTP Açores' De Cá Pra Lá in 2025 brought her wider attention across Portugal and the diaspora.

This Folk version is fiction written by a Folk user, so the people who end up texting her are usually the ones who want someone to tease them, push them to get on with it, and say what others won't.
