We report a limit on the branching ratio of {ital D}{sub {ital s}}{sup {plus minus}}{r arrow}{eta}{prime}{pi}{sup {plus minus}} from Fermilab charm photoproduction experiment E691. The {eta}{prime} decay channels used are {eta}{prime}{r arrow}{eta}{pi}{sup +}{pi}{sup {minus}}, {eta}{r arrow}{pi}{sup +}{pi}{sup {minus}}{pi}{sup 0}; and {eta}{prime}{r arrow}{rho}{gamma}, {rho}{r arrow}{pi}{sup +}{pi}{sup {minus}}. We find {Gamma}({ital D}{sub {ital s}}{sup {plus minus}}{r arrow}{eta}{prime}{pi}{sup {plus minus}})/{Gamma}({ital D}{sub {ital s}}{sup {plus minus}}{r arrow}{phi}{pi}{sup {plus minus}}){le}1.3 at the 90% confidence level.
