Catharina Charlotta Löfgren (January 1720, Linköping – 14 February 1784), was a Swedish lady of letters and poet.
She lived in Norrköping from 1746, where she was a local literary celebrity and wrote poems for festive public occasions.
Löfgren was published both in name and anonymously, which means that a significant amount of her poems are unidentified.
Löfgren has been identified with the pseudonym Climene, to whom Hedvig Charlotta Nordenflycht addresses a poem in the form of a letter from 1759, which is counted as a sketch to the latter famous feminist poem Fruentimrets försvar (The Defense of Women), where Nordenflycht defense the intellectual capability of females and states that intellectual inferiority is caused by the lack of education and knowledge rather than the natural effect of gender.
Nordenflycht was enthusiastic in her ambition to encourage literary talent in other females, and was reportedly happy about the female collective of writers in Norrköping, which consisted of Löfgren, Hedvig Löfwenskiöld, Hedwig Walldorff and Margareta Gryzell.
