Founded in 1879 as Cumberland, the club played in a senior Competition with University, Wallaroos, Waratah, Redfern and Pirates until 1899 when the existing system was disbanded.

Former Wallaby Rod Phelps took over as captain-coach in 1971 and for three years he improved Parramatta‘s standing in the rugby fraternity.

Finally with the influx of young players in this period Parramatta won its initial First Grade premiership in 1977, a 17–9 victory against Randwick under coach Peter Fenton.

The Club then played in the 1979 and 1984 grand finals going down to Randwick on both occasions, but revenge would be sweet in 1985 and 1986 when the underdogs from Sydney’s west succeeded in beating the Galloping Greens to win consecutive premierships under coach Paul Dalton.
