Robert IV of Artois (1356 – 20 July 1387), son of John of Artois, Count of Eu and Isabeau of Melun, was Count of Eu from April to July 1387 and Duke of Durazzo from 1376 to 1383.

About 1376, he married Joanna of Durazzo, daughter of Charles, Duke of Durazzo. Robert became the Duke of Durazzo through the right of his wife until 1383 when Karl Thopia took over Durrës. Robert inherited the County of Eu upon his father's death on 6 April 1387, along with Saint-Valery and Ault. However, as he was in Naples at the time, he never learned of his father's death nor did he rule his lands. On 20 July 1387, he and his wife were poisoned on the orders of Joanna's own sister Margaret, Queen Regent of Naples, while they were staying at Castel dell'Ovo. Robert and Joanna were buried in the church of San Lorenzo Maggiore in Naples.

The marriage of Robert and Joanna was childless. Robert was succeeded in his titles by his younger brother, Philip.
