There are provided simple processes for preparing a fluoroamide and a fluoronitrile which assure higher yield, i.e., a process for preparing a fluoroamide represented by the formula (2): CF
2
═CF—R
f
—CONH
2
, wherein R
f
is a perfluoroalkylene group or perfluorooxyalkylene group having 2 to 20 carbon atoms, by allowing a fluoroester represented by the formula (1): CF
2
═CF—R
f
—COOR, wherein R
f
is as defined above; R is an alkyl group having 1 to 6 carbon atoms, to react with ammonia or ammonium hydroxide, and a process for preparing a fluoronitrile represented by the formula (3): CF
2
═CF—R
f
—CN, wherein R
f
is as defined above, by allowing the fluoroamide obtained by the above-mentioned preparation process to react with a dehydrating agent (c) in a solvent (b) having an ether bond, an ester bond, a ketone group or a cyano group.
