MacAlley and McAlley are unisex surnames in the English language. There are several origins for the names.
Both surnames can be derived from several Gaelic surnames.
In some cases the surnames are derived from the Scottish Gaelic MacAmhalghaidh. This name translates into English as "son of Amhalghaidh", or "son of Amhalghadh". The surname originated as a patronym, however it no longer refers to the actual name of the bearer's father.
