Declan Ryan (born 1968) is an Irish former hurler and team manager with Tipperary.
Regarded as one of his county's greatest hurling servants, Ryan joined the team during the 1988 championship and was a regular member of the team until his retirement after the 2001 championship. During that time he won three All-Ireland medals, five Munster medals and four National Hurling League medals. He has ended up as an All-Ireland runner-up on two occasions.
At club level Ryan is a two-time county club championship medalist with Clonoulty-Rossmore.
In retirement from playing Ryan became involved in team management. He guided the Tipperary minor hurling team to a second consecutive All-Ireland title in 2007 before later winning back-to-back Munster titles with the Tipperary senior hurling team. An All-Ireland title eluded the team and Ryan stepped down as manager after two years in September 2012.
