Hilkka Terttu Hilda Toivola (20 June 1909 – 19 September 2002) was a Finnish artist who created many stained-glass works, particularly for churches.

Toivola also studied with glass painters Giovanni Toller in Florence (1938) and Pierre Gaudin in Paris (1951).

Toivola married the painter Otso Karpakka (1914-2005); both were involved in Ryhmä 9, a Turku-based artists' collective that functioned from 1951 to 1959.

The couple were unusual in having worked alongside each other as artists for some 60 years, cooperating in the creation of several large frescoes and stained-glass pieces.
