假钞，亦称伪钞，英文可以表达为“fake money”或“counterfeit money”或“bogus money”，是指伪造、变造的货币，伪造的货币是指仿照真币图案、形状、色彩等，采用各种手段制作的假币，变造的货币是指在真币的基础上，利用挖补、揭层、涂改、拼凑、移位、重印等多种方法制作，改变真币原形态的假币。

“Bogus money”中bogus一词的来源：

美国马萨诸塞州波士顿的一份新闻报刊认为，该词是从意大利臭名昭著的骗子鲍格才（ Borghese ）的名字演变而来的。他行骗有术，手段高明，擅长开空头支票，到银行或商店里去兑换现金。由于开了一大把不值分文的支票、汇票和其他票据，鲍格才出了名。从他的大名 Borghese 也就逐渐成了“冒牌的”或“伪造的”的同义词，后来拼写形式缩写为 bogus 。

伪造货币罪（crime of counterfeiting），是指没有货币制作、发行权的人，非法制造外观上足以使一般人误认为是货币的假货币，妨害货币的公共信用的行为。
