Horta Sud (Valencian: [ˈɔɾta ˈsut], also [ˈɔɾtɔ ˈsut]; Spanish: Huerta Sur [ˈweɾta ˈsuɾ]) is a comarca in the province of Valencia, Valencian Community, Spain, to the south of the city.

Due to the arrival of numerous Spanish-speaking immigrants in the 60s and 70s, the percentage of Valencian speakers has been reduced in many municipalities.

Even so, it is the sub-region with the greatest knowledge and use of Valencian in the metropolitan area of Valencia.

[3] At the end of October 2024, the region suffered catastrophic flooding, and the heaviest impact in all of Spain, due to the October 2024 Spain floods, which swept away roads, bridges, cars and homes, leaving more than 200 dead and many hundreds more homeless.

The community, deeply affected, now faces the challenge of rebuilding in the midst of a humanitarian emergency.
