Bus services in Oxford and its suburbs are run by the Oxford Bus Company and Stagecoach Oxfordshire as well as other operators including Arriva Shires & Essex and Thames Travel.

Arriva Shires & Essex operates Sapphire route 280 to Aylesbury via Wheatley, Thame and Haddenham seven days a week, at a frequency of up to every 20 minutes.
The new Sapphire buses have three-pin power sockets, leather seats and free, onboard Wi-Fi.

Oxford has five park and ride car parks with frequent bus links to the city centre:
Pear Tree (bus 300)
Redbridge (bus 300)
Seacourt (bus 400)
Thornhill (bus 400)
Water Eaton and Oxford Parkway (bus 500)
There are also bus services to the John Radcliffe Hospital (from Thornhill and Water Eaton/Oxford Parkway) and to the Churchill and Nuffield Hospitals (from Thornhill).
As of 2015, Oxford has one of the largest urban park and ride networks in the UK.
Its five sites have a combined capacity of 4,930 car parking spaces, served by 20 Oxford Bus Company double deck buses with a combined capacity of 1,695 seats.
By comparison, York park and ride has six sites with a combined total of 4,970 parking spaces served by 35 First York buses, but they are single deckers with a combined capacity of 1,548 seats.

More than 58% of Oxford Bus Company customers use the ITSO Ltd smartcard.
Secondary school students are able to gain either a reduced price pass, like pay a set fee for the month, or a free riding pass for the school year.

In November 2014 all Oxford Bus Company buses within the Oxford SmartZone area have free WiFi installed.

Hybrid buses, which use battery power with a small diesel generator, began to be used in Oxford on 15 July 2010, on Stagecoach Oxfordshire's Route 1 (City centre – Cowley – Blackbird Leys).
Both Stagecoach and Oxford Bus Company now operate numerous hybrid buses in the city.
In 2014 Oxford Bus introduced a fleet of 20 new buses with flywheel energy storage (FES) on the services it operates under contract for Brookes University.
Whereas electric hybrids use battery storage and an electric motor to save fuel, FES uses a high-speed flywheel.
