Erica Hartmann (エーリカ・ハルトマン, Ērika Harutoman?) is a witch of the 501st Joint Fighter Wing, originating from Karlsland. Her familiar is the Dachshund.
Erica is Karlsland's sixteen year old "ultra ace" of the Luftwaffe JG 52 with more than 300 confirmed victories and the rank of Flying Officer. Within the setting of the Strike Witches' world, she one of the best-seven witches in terms of shot down count. While extremely efficient and strategic in battle, Erica is rather sloppy on the ground, and her room (which she has never cleaned) is extremely messy. She is the sort of person who is only serious when the situation calls for it.
Her ace archetype is Erich Hartmann. Erica's hairstyle is based on Erich's nickname "Bubi". She has her hair in a "Bubischnitt", which is the German term for a "bob".
