Acacias 38 is a Spanish soap opera television series produced by Boomerang TV for Televisión Española (TVE) that originally aired on La1 from 2 April 2015 to 13 May 2021. The fiction is set in building 38 Acacias Street, in Madrid. The start of the series was set in 1899. By the fifth season, it was set in 1913. The seventh season took a 5-year time leap to 1920.

In March 2020, the filming was interrupted due to the health emergency of the COVID-19 pandemic in Spain, to then restart in mid-May. To avoid running out of chapters, TVE aired half an episode of the series every day, for a total of two and a half chapters per week. From 15 June 2020, the series will reissue the full chapters after the return of the actors to the filming. On 29 January 2021, the cancellation of the series was announced, which would end its filming in March and its broadcasts in May. Days later, TVE reported that a spin-off of the series is being studied focused on the love of Camino (Aria Bedmar) and Maite (Ylenia Baglietto) in Paris, which had already sparked a spin-off in podcast format, #Maitino: el podcast.
