Enrique Nieto y Nieto (October 6, 1880 or 1883 – January 20, 1954) was a Spanish architect known for his Modernisme style (not to be confused with modernism), which he continued to receive commissions to design even after it fell out of favor.
He was a student of Antoni GaudĂ and followed his master's style when he designed noted projects in Barcelona and Melilla.
In 1939, he was appointed city architect of Melilla, a Spanish enclave in North Africa.
Mellila's collection of modernisme-style buildings constitutes the second largest concentration of representatives of the style outside of Barcelona.
