The 25-year-old Irishman arrives at Huish Park on a free transfer after having his contract cancelled by the Robins.
"As soon as I was made aware that Brendan was available, we moved quickly," Yeovil boss Gary Johnson is quoted as saying by BBC Sport.
Moloney made 58 appearances for Bristol City following a move from Nottingham Forest in January 2013.
