Louise Nathalie Adelborg (2 July 1885 – 9 September 1971) was a Swedish porcelain designer and textile artist.

She was the daughter of Jacquette De Geer and Otto Ehrenfrid Adelborg, a Swedish Army captain.

She graduated from the Technical School in Stockholm, following up with study trips to Italy and France.

She began exhibiting ceramics and embroidery in 1916, and around the same time was tapped as a designer of patterns for the Rörstrand porcelain factory.

She continued working for them until 1957, developing into a highly respected designer known for "an understated yet graceful modernism".
