Count Alajos Károlyi de Nagykároly (August 8, 1825 – December 2, 1889), was an Austro-Hungarian diplomat.
He was born in Vienna, into the great Hungarian family of Károlyi, whose fame dates from the time of Sándor Károlyi (1668-1743), one of the generals of Francis II Rákóczi, who in 1711 negotiated the peace of Szatmár between the insurgent Hungarians and the new king, the emperor Charles VI, was made a count of the Empire in 1712, and subsequently became a field marshal in the imperial army.
Alajos Károlyi entered the Austrian diplomatic service, and was attached successively to embassies at various European capitals. In 1858 he was sent to Saint Petersburg on a special mission to seek the support of Russia against Napoleon. He was ambassador at Berlin in 1866 at the time of the rupture between Prussia and Austria, and after the Seven Weeks War was responsible for the negotiation of the preliminaries of peace at Nikolsburg. He was again sent to Berlin in 1871, acted as second plenipotentiary at the Berlin congress of 1878, and was sent in the same year to London, where he represented Austria for ten years. He died at Tótmegyer.
