A search for Cepheids in NGC 4414 has been performed using HST archive data. Accurate photometry for this galaxy is challenging due to its high surface brightness background with steep gradients and the rather low S/N of stellar point sources. The photometry package ROMAFOT has been used, and the results compare favorably with published photometry reported by Turner et al. (1998). All eleven Cepheids were recovered and nine additional candidates were discovered. The resulting distance modulus of 31ṃ50±0ṃ27 is only 0ṃ1 larger than previously reported.
