Titus Viorel Popovici (16 May 1930 – 29 November 1994) was a Romanian screenwriter and author.^[1]

He graduated from the University of Bucharest in 1953. Two years later, he published his first novel, Străinul (The Stranger). His first screenplay appeared in 1957. It was an adaptation of the novel Moara cu noroc (The Lucky Mill) by Ioan Slavici. From then on, he concentrated on screenwriting, working with prominent directors such as Liviu Ciulei, Andrei Blaier, Manole Marcus and Sergiu Nicolaescu.

In 1974, he became a corresponding member of the Romanian Academy and joined the Writers' Union of Romania. He was also a member of the Central Committee of the Romanian Communist Party and served in the Great National Assembly as a Deputy from Bihor County.

He died as the result of an automobile accident near Tulcea. It was later suggested that his death was not accidental but, rather, that he was eliminated because he knew too much about the Party's former Nomenklatura.^{[citation needed]}

A street in Oradea was named after him in 2002.
