Elvira Eliza Clain-Stefanelli (; 1914-2001) was a numismatist, director of the National Numismatic Collection of the Smithsonian Institution, and advisor to the US Mint.

Biography 
She was born in Bucharest, Romania and studied history at Franz Joseph University. She received a masters degree in history at the University of Cernauti. In 1939, she married Vladimir Clain-Stefanelli (1914-1982), whom she met in Rome. The Clain-Stefanellis later moved to Berlin and were conducting research on coins in 1943 when they were sent to the Buchenwald concentration camp because Vladimir's passport had been stolen and used by an "enemy of the state."

The Clain-Stefanellis emigrated to the United States in 1951. Elvira worked at Stack's Coin Galleries before joining the Smithsonian Institution in 1957, where Vladimir had been curator of the Division of Numismatics for one year. Over her several decades at the Smithsonian, she grew the National Numismatic Collection (NNC) from approximately 60,000 pieces in 1956 to over 960,000 pieces in 1982. She was appointed Executive Director of the NNC in 1983 and served in that role until her retirement in 2001.

In addition to her curatorial role at the Smithsonian, Clain-Stefanelli was an accomplished author, especially noted for her Numismatic Bibliography (1984), a work listing over 18,000 publications on all facets of numismatics.

In 1994, Clain-Stefanelli was appointed to the newly-formed Citizens Commemorative Coin Advisory Committee (the predecessor of the Citizens Coinage Advisory Committee), which was created by Congress to advise the Secretary of the Treasury on commemorative coin programs. She served on the committee until her death in 2001.
