钕（旧译作釢、鋖）是化学元素，化学符号是Nd，原子序数是60，属于镧系元素(稀土元素)。1885年由冯·韦尔塞巴赫发现。银白色金属，较活泼，室温下在空气中缓慢氧化，能与水和酸作用放出氢。有顺磁性。存在于独居石中，由含水氯化钕经脱水后用金属钙还原，或由无水氯化钕经熔融后电解而制得。用于制造特种合金、电子仪器和光学玻璃。在制造激光器材方面，有着重要的应用。

Neodymium is a chemical element with symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a "rare earth", it is a fairly common element, no rarer than cobalt, nickel, and copper, and is widely distributed in the Earth's crust. Most of the world's commercial neodymium is mined in China.
