What to KnowIn modern established use, drank is the past tense of drink ("I drank a glass of water"), and drunk is the past participle ("I have drunk three glasses of water today"). Throughout the long history of the word drink, however, there have been centuries when the two forms were used in the opposite contexts, and in some dialects today they still are.
Perhaps you have, at some point, found yourself saying "I have drank..." or "I had drank...." Pretty reasonable. Or maybe you’ve used drunk rather than drank in the past tense while recounting a night out, or a very nice tea party. Also within the bounds of reason. So ... which time were you being grammatically correct?

Though technically incorrect, drank used as a past participle (the form of the verb used with be or have, as in "I have never drank coffee") is not unheard of in speech, and drunk occasionally is heard in place of drank as a past-tense verb (“I lied before—I drunk a cup of coffee once”). Inflections of the irregular verb drink have seen unsteady use for centuries—even in writing.
The History of 'Drank' and 'Drunk'
According to the set rules for irregular verbs, drank indicates the past tense and drunk is the past participle. Other similar inflections are rang and rung for ring and sang and sung for sing. The Oxford English Dictionary notes, however, that drunk was accepted in past-tense usage from the 16th through the 19th centuries, and British Lexicographer Samuel Johnson gives past-tense drunk as a standard variant in his 1755 A Dictionary of the English Language.

On the flip side, drank as a past participle showed up during the 17th century, and it seems to have been commonly used in writing throughout the 19th century.

It’s been suggested that this substitution of drank for drunk originated as a way to avoid the association of drunk with intoxication. Given the social emphasis on morality in past times, that thought seems sensible; however, saying "I had drank too much wine" doesn't hide the fact that you did indeed. Nevertheless, it is likely that this intentional avoidance of the word continues today.
Writers of early 20th-century handbooks, striving to make irregular verb inflection uniform in English, thought differently about drunk and prescribed it as only a past participle of drink that should be criticized when used for past tense.
Correct Usage of 'Drank' and 'Drunk'
Modern handbooks only recognize drunk as the past participle, so you will want to use the past drank and the past participle drunk in writing. Use of drunk as the past tense is essentially dialectal and outside of dialect is considered incorrect.
… I ain't got no money for to buy the outfit, and I reckon I couldn't get none from home, because it's likely pap's been back before now, and got it all away from Judge Thatcher and drunk it up.
— Mark Twain, Adventures of Huckleberry Finn 1884
Drank, on the other hand, has gained a level of acceptance in spoken use.
Another phrase you may have heard is "I have/had drunken too much," as drunken was once a past participle of drink. However, since the 17th century, it has been mostly used as an adjective, and its function as a verb is now deemed archaic. Today, drunken is chiefly used attributively, as in "drunken partiers" or "a drunken brawl," and is a complement to the adjective form of drunk.
