A method for producing a fluorene derivative by reacting fluorenone with a phenol or a phenoxyalcohol in the presence of an acid catalyst includes: adding an alkali to an obtained reaction liquid containing a fluorene derivative; and concentrating a resultant mixture liquid without removing the alkali thus added and a reaction product of the alkali, thereby separating an unreacted phenol or unreacted phenoxyalcohol.
