Apostolic Succession in the Catholic church Wikipedia says:


  In the Catholic Church, the Pope is regarded as the successor of Saint
  Peter, the Apostle.
  cf. Pope | Wikipedia


As someone who isn't Catholic I don't want to argue how true this is or how significant this is.

What I'm interested to know is there an office/title/person in the Catholic church for any of the other 11 Apostles (12 if you include Paul), or is it just Saint Peter because he was the leader of the apostles?
The other apostles are associated with other Churches. St Mark, for example, was the founder of the Church of Alexandria; St Thomas is believed to have taken Christianity to India; and so on. Only St John the Evangelist did not die a martyr in a far-off place (at least, Patmos isn't as far as India).

Accordingly, most of the other apostles do not have such a place as Peter's within the Roman Church, but they do have a similar position as Patriarchs of the Churches they founded.
