Delphinidin (also delphinidine) is an anthocyanidin, a primary plant pigment, and also an antioxidant. Delphinidin gives blue hues to flowers in the genera Viola and Delphinium. It also gives the blue-red color of the grape that produces Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries.

Delphinidin, like nearly all other anthocyanidins, is pH-sensitive, i.e. a natural pH indicator, and changes from red in acidic solution to blue in basic solution.

Several glycosides derived from delphinidin are known.

Myrtillin (delphinidin-3-O-glucoside) and tulipanin (delphinidin-3-O-rutinoside) can be found in blackcurrant pomace.

Violdelphin (delphinidin 3-rutinoside-7-O-(6-O-(4-(6-O-(4-hydroxybenzoyl)-β-D-glucosyl)oxybenzoyl)-β-D-glucoside) is responsible for purplish blue flower color of Aconitum chinense.
Nasunin (delphinidin-3-(p-coumaroylrutinoside)-5-glucoside) is responsible for the colour of the eggplant fruit purple skin.
