Professor Ambroży Kleks (English: Ambrose Inkblot), commonly referred to as Pan Kleks (English: Mr. Inkblot or Mr. Blot), is a fictional character in the Pan Kleks series, a trilogy of books written by Polish author Jan Brzechwa. He is depicted as the founder and headmaster of a magical academy for wizards that is attended by boys whose names begin with the letter "A". Kleks is depicted as a tall and eccentric man with a bushy beard, who wears a velvet frock coat over a waistcoat with numerous pockets. Among his magical abilities is his ability to change his size.

The character was partly based on Franciszek Fiszer, a Polish metaphysician and alchemist known to the literary circles of pre-World War II Warsaw.

Kleks was portrayed by Piotr Fronczewski in three films based on the book series, each of which were directed by Krzysztof Gradowski: Akademia pana Kleksa (1983), Podróże pana Kleksa (1986) and Pan Kleks w kosmosie (1988). Fronczewski also voiced the character in the 2001 animated film Tryumf pana Kleksa.
