Hariclea Darclée (née Haricli; later Hartulari; 10 June 1860 – 12 January 1939) was a celebrated Romanian operatic spinto soprano of Greek descent who had a three-decade-long career.

Throughout her career she participated in several world premieres, creating the title roles in Giacomo Puccini's Tosca, Pietro Mascagni's Iris, and Alfredo Catalani's La Wally.

She married a young officer, Iorgu Hartulari, and became known for a while as Hariclea Hartulari-Darclée, Darclée being the nom de théâtre she adopted when she made her debut at the Paris Opéra in 1888 as Marguerite in Charles Gounod's Faust.

In 1890, Darclée scored a great success in her La Scala debut as Chimène in Jules Massenet’s Le Cid, and was immediately engaged by all the leading Italian theatres.

Highlights of her later career in Italy from 1890 on included the world-premières of the part of Odalea in Antônio Carlos Gomes' Condor at La Scala in Milan in 1891, the title-role in Alfredo Catalani's La Wally at the same theater in 1892, Luisa in Pietro Mascagni's I Rantzau at the Teatro della Pergola in Florence in 1892, and the title roles in Pietro Mascagni's Iris and Giacomo Puccini's Tosca, both at Teatro Costanzi in Rome in 1899 and 1900, respectively.
