Jared Rosser has made 74 senior appearances for the Men of Gwent, since his professional debut in 2017.
The 25-year-old – who can also operate at centre – has scored 27 tries for the club, putting him fifth on the all-time list.
Ewan Rosser has impressed for Wales Under-18s, Wales Under-20s and Wales Sevens, including playing in the Rugby World Cup Sevens in Cape Town in 2022.
The 22-year-old – who has featured for Pontypool in the WRU National Championship this season – has signed a new Senior Academy contract that will see him train in the senior set-up.
Head Coach Dai Flanagan said: “We’re pleased that two exciting homegrown talents have agreed new terms to continue their development with us.
“Jared is firmly established in the senior set-up with an outstanding try scoring record. He has also shown real leadership qualities in my time at the club.
“Ewan is a talented young man who has been outstanding for Pontypool and is keen to really kick on next season.
“We’re determined to promote the best young talent that comes through our Academy set-up and both Jared and Ewan are great examples of young Gwent men who want to achieve with Dragons.”
