Kent youngsters Daniel Bell-Drummond and Sam Billings are among nine players to sign new contracts with the club.
Adam Ball, Alex Blake, Charlie Hartley, Matt Hunn, Imran Qayyum, Adam Riley and Darren Stevens have also extended their deals at Canterbury.
"This year has shown the potential of the team emerging both at an individual and a team level," chairman of cricket Graham Johnson said.
"The exciting thing for the future is that there is so much more to come."
Billings, 23, was the fourth highest run-scorer in the One-Day Cup this season, scoring 458 runs at an average of 114.50, while Bell-Drummond, 21, has scored over 900 runs in the County Championship, averaging above 39.
Experienced all-rounder Stevens, 38, has impressed with bat and ball in the four-day format, scoring over 800 runs and taking over 50 wickets.
Kent have not disclosed the length of the deals for the nine players, while academy scholars Ryan Davies and Sam Weller will also join the senior squad for the first time.
"It is very encouraging to have all these players wanting to build on this year and commit to Kent," Johnson added.
"With them on board forming the core of our squad going forward and defining our future, Kent supporters should feel enthusiastic about what we can achieve."
