Arnold Charles Ernest Hintjens (born 21 May 1949), best known as Arno Hintjens or simply Arno, is a Belgian artist born in Ostend. He was the frontman of TC Matic, one of the best-known Belgian bands of the 1980s. After the band split in 1986 he had a successful solo career.
Hintjens, who neither claims to be a singer or an intellectual, sings in a mixture of English, French and his Ostend dialect. For TC Matic, a band which achieved moderate artistic success throughout Europe, he wrote or co-wrote all the band's material, much of it together with guitarist and producer Jean-Marie Aerts. After going solo he released more than a dozen albums during a successful career. In 2002 he received the title "Chevalier des Arts et des Lettres" (Knight in the Arts and Literature) of the French government. A 2004 biography by Gilles Deleux was translated in Dutch as Een lach en een traan ("A Smile and a Tear").
In the Belgian movie Camping Cosmos he played the homosexual lifeguard Harry who does not pay attention to Lolo Ferrari who is incarnating a caricature of Pamela Anderson.
