Hedvig Charlotta Raa-Winterhjelm, née Forssman (20 November 1838 – 7 March 1907), was a Swedish actress active in Sweden, Norway and Finland.

She studied at the Royal Dramatic Training Academy in Stockholm in 1854–56, after which she toured in travelling theater companies in Sweden and Finland.

The Swedish Theatre in Helsinki was the first permanent theater in the city: inaugurated in 1860, it had burned down in 1863 and was reopened in 1866, when Raa-Winterhjelm was employed there.

The theater became the first national stage in Finland, and Charlotta Raa-Winterhjelm became its lead actress within romantic tragedy between 1866 and 1872.

This was however opposed by the Russian authorities, who banned her from accepting assignments in the Finnish language, and the same year, she left with a travelling theater company to perform in Oslo in Norway.

Her second spouse was an alcoholic who forbade her to accept long-term assignments, and she continued her career as a guest artist.
