Marita Stolze is a German puppeteer who played Tiffy on Sesamstrasse from 1989 until 2000.

Puppeteers Karime Vakilzadeh and Karin Kaiser played the character's right hand. Stolze inherited Tiffy from puppeteer Kerstin Siebmann-Röders and handed her over to puppeteer Sabine Falkenberg, who eventually retired the character after 27 years on the show in 2005.

Stolze performed the character on the 1993 international special Sesame Street Stays Up Late!.
