The announcement was made at the Falcons' season launch last night.
Murphy akes the reins from 2014 skipper Ryan Hansen.
The new captain, 23, has risen quickly since joining the club mid-season last year from the Canterbury Bulldogs, culminating in a four-week training stint with the Melbourne Storm in December.
Murphy was mentored by premiership-winning coach Craig Bellamy, who described the back-rower as the best young trainer he had seen.
Falcons chief executive Chris Flannery said Murphy had all the qualities befitting a captain.
"Tom is a very big part of this club and we made it our priority to build a team around him," he said.
"His toughness is one of the things that stands out, as well as his desire to win - he wants to win everything and is competitive in everything he does.
"He's a leader anyway, whether he has the captaincy next to his name or not."
Murphy grew up playing junior footy on the Coast before attending boarding school in Rockhampton.
He picked up a youth contract with the Canberra Raiders and starred alongside current NRL stars Josh Papalii and Jack Wighton in the national capital's youth academy.
He then joined Redcliffe in 2012 and helped the Dolphins to that year's Intrust Super Cup grand final.
Murphy secured a contract with Canterbury at the start of 2014, but injured his ankle in a trial match and was subsequently released by the club.
"He wanted to come home and be closer to his family and play footy here," Flannery said.
Flannery who played for Queensland and won a premiership with the Roosters in 2002, said Murphy possessed the necessary qualities to progress to the NRL.
"When Bellamy was here he gave him huge wraps," Flannery said. "I am sure if the Storm does get a few injuries this year that Tom will definitely be on the radar.
"He is like a (Ryan) Hinchcliffe-type player who gets the job done, and that is what coaches, particularly Bellamy, want."
