The present invention provides a modified cellulose that is excellent in dispersibility for a resin and is useful as a composite material of a resin, a method for producing the same, and a resin composition containing the modified cellulose. In the presence of at least one acid selected from Bronsted acid, solid acid and Lewis acid having an acid dissociation index pKa in an aqueous solution of −9 to 5 at 25 ° C., cellulose and the following formula (1): By reacting with the fluorene compound represented, the fluorene compound binds to the cellulose, and a modified cellulose having a powdery form is obtained. (In the formula, ring Z is an arene ring, R 1 is an alkylene group, R 2 and R 3 are substituents, k is an integer of 0 to 4, p is an integer of 0 or 1 or more, m is 0 or 1 or more of And n is an integer of 1 or more.)
