Amelita Galli-Curci Estate, also known as Sul Monte, is a historic country estate located near Fleischmanns, New York, straddling the boundaries of Delaware County and Ulster County, New York.

The architect Harrie T. Lindeberg (1879–1959) designed it as a country home for Italian operatic soprano Amelita Galli-Curci (1882–1963).

The main house, built in 1922, is large and rambling, two-stories high, with multiple wings that wrap around a central courtyard.

The structure is wood-frame construction sitting on a concrete foundation, its walls clad in variegated stone, stucco and wood, and its steeply-pitched roof clad with cedar shingles.

Other contributing buildings and structures include the swimming pool, stone gateposts, sheds, caretaker's cottage and dairy barn.
