The Fairs Act 1204 is still in force in Ireland.
The Islamic laws (also called sharia) which appeared ca. 710 AD and still applied in some countries like Saudi Arabia, where the Koran is the official constitution of the kingdom.
Chapters 1, 4, 15 and 23 of the Statute of Marlborough 1267, an Act of the English Parliament, are still in force in the UK.
Chapter 1:
criminalised the taking of “revenges” or the levying of distress without first obtaining a court order.
Chapter 4:
prohibited the taking of distrained goods or belongings out of the debtor’s home county, particularly where the removal was carried out by a landlord against his tenant
Chapter 15:
made it unlawful for anyone to distrain on the public highway
Chapter 23:
made it illegal for “fermors” deliberately to “make waste, sale, or exile” (without written permission) of any house, woods, men or any other thing belonging to tenements demised to them.

(Quotes are from the above report; see also here, here and here.)
UPDATE, Jan 2016: A subsequent Law Commission report found that chapter 15, and part of chapter 4, have now been superseded and can be repealed (though at the time of writing, this has not yet happened). Chapters 1 and 23 "appear to have continuing value".
A rather old set of laws still in force, are the canons promulgated by the First Ecumenical Council in Nicaea of 325. There were twenty canons of which some were later amended while others still in force in the Christian Church. One of the canons was Canon 1 for the prohibition of self-castration for Christians.
Another set of canons were adopted in the Second Ecumenical Council in Constantinople in 381. This includes the Niceno-Constantinopolian Creed which is still in use by the Orthodox church and the Catholics who pray in Greek.
