The Bergianska trädgården, the Bergian Garden or Hortus Bergianus, is a botanical garden located in the Frescati area on the outskirts of Stockholm, close to the Swedish Museum of Natural History and the main campus of Stockholm University.

The Garden was founded through a donation in 1791 by the historian and antiquarian Bengt Bergius and his brother Peter Jonas Bergius, a physician and scientist, for the Royal Swedish Academy of Sciences, and was originally located at their mansion and its adjacent garden on the Karlbergsvägen road, in what is now the Vasastaden district in central Stockholm.

The Garden was donated to the Royal Academy after the brothers' death in 1791, in accordance with their will.

It is jointly administered by the Academy of Sciences and Stockholm University.
