Ladislaus (I) Losonci (Hungarian: Losonci (I.) László; died January–February 1392) was a powerful Hungarian baron, who served as Count of the Székelys from 1373 to 1376, and Voivode of Transylvania from 1376 to 1385 and from 1386 until his death. He was a staunch supporter of Mary, Queen of Hungary after 1382. In contemporary records, he was often called Ladislaus the Elder to distinguish him from his namesake relative Ladislaus II Losonci.
