Oriel College Boat Club (OCBC) is the rowing club of Oriel College, Oxford. Rowing at Oriel is carried out from the college's own boathouse across Christ Church Meadow, on Boat House Island.

Oriel is the most successful rowing college in Oxford, having won the most men's 1st VIII headships of any college at the two intercollegiate bumps races: Torpids and Eights Week (Summer Eights). Since 1976, Oriel has enjoyed a particular period of dominance in these events. The club's women's 1st VIII has also won two Torpids headship since the admission to women to the college in 1986.

In men's rowing at short races, bumps, this is the most successful Oxford college boat club. As of 2020, Oriel holds 37 Torpids Headships, by a large margin, the most of any college and 33 Summer Eights Headships.

From 1972 to 1998 Oriel's Men's First Boat was undefeated in Torpids, the longest run of any college by far. In 2006 Oriel claimed the first ever double headship in Torpids, rowing over as Head of the River in both the men's and women's first divisions. In 2018 Oriel repeated this victory with their second double headship. It is the only college to possess a double headship in Torpids.

The women's and men's second boats have long been in "fixed divisions" in the bumps charts and, as such, are guaranteed a place in racing each year. The college usually fields third boats (and sometimes more) for the bumps events. More extensive information on the results of Torpids and Eights can be found here: Oxford Bumps Charts

In addition to the Oxford-based races, Oriel crews compete in external events including the Fairbairn Cup, the Head of the River Race, the Women's Eights Head of the River Race, the Henley Boat Races and many regional and national events.

In 2016 the men's first boat won the men's eights collegiate event at the Fairbairn, it won again in 2017 and won the entire event in 2018.

The general emblem of the Oriel College Boat Club is the three ostrich feathers, an example of Oriel College's use of the Prince of Wales's feathers. In recent years this has been augmented by the addition of crossed-oars below the feathers. The first boats row under the emblem of the Tortoise Club, detailed below, a tradition established from when OCBC would race at external regattas as The Tortoise Club. The boat club's colours are the same as the college's: two white stripes on navy.

Until 2009 the wearing of Boat Club Jackets (ivory with navy blue piping and cuff rings, bearing the three ostrich feather emblem on the left breast) was limited to the 1st and 2nd Summer VIII's and Torpids and the Oriel College Boat Club Committee. At that time cuff ring designations were: Three rings for 1st Summer VIII and 1st Torpid; two rings for Boat Club Committee; one ring for 2nd Summer VIII 2nd Torpid. These now obsolete designations can still be seen at the Walters of Oxford website.

Changes brought about in the Oriel Blazer Act of 2009 to become more inclusive of lower-boats' alumni (3rd, 4th, and sometimes 5th VIII's as well as boat coxswains) reformed the cuff ring designations as follows: Three rings for 1st Summer VIII; two rings for 1st Torpid and those awarded Tortoise membership at the Tortoise Council's discretion; one ring for general boat club members (no specific distinction for committee members exists today).

In Tom Brown at Oxford by Thomas Hughes, Oriel's win in the 1842 Head of the River Race, with Oriel bumping Trinity, was re-written as Tom's college, "St Ambrose" taking first place and "Oriel" in second place.

Oriel College, in particular the Boat Club Captains' rooms, as well as Oriel memorabilia and references are also present in Oxford Blues (1984) and True Blue (1991).

During the 7th week in Trinity Term, OCBC hosts the annual Oriel Regatta; events in this competition are Mixed Eights and Crewdate Eights. Mixed Eights are crews from a single college that must contain at least four women rowers. For Crewdate Eights one enters as a group of four rowers with or without a coxswain and are then matched up with another group, where possible creating a mixed college and mixed gender crew. The final two crews have a crewdate paid for them by the Regatta. It is a fun event with which to end the year's collegiate racing schedule. The course runs upstream from the Longbridges Boathouse to past the end of boathouses on Christ Church Island and races are conducted in knock-out format.

The purpose of the Tortoise Club is two-fold: the recognition and celebration of outstanding Oriel rowing; and the financial support of the OCBC. Membership is by election: proposal by the Men's Captain of Boats, Women's Captain of Boats and the President of the Tortoise Club. Election is by the approval of the Tortoise Council. Members must be Orielenses (excepting Honorary members) who have represented OCBC with excellence.

A grant of a Badge was made to The Provost and Scholars of the House of the Blessed Mary the Virgin in Oxford commonly called Oriel College of the Foundation of Edward the Second of famous memory sometime King of England, for the use of Oriel College Boat Club, the Tortoise Club and the Oriel Society, by Letters Patent dated 20 April 2009 of Garter, Clarenceux and Norroy & Ulster Kings of Arms.

This was an exclusive, women's alumni club. Since 2016, women are now admissible into the Tortoise Club on the same terms as men so the club is defunct. This was particularly controversial to many members of the Tortoise Club as a separate boat club was created for the women of the college in 1986, rowers in their 1st VIII and 1st Torpid became members of this club mutatis mutandis to the Tortoise Club. The respective unique emblem was a pair of (angelic) wings. The "Blessèd Virgins" was a nod to a name of the college as still seen in some registers of title and official documents today, The House of Blessèd Mary the Virgin in Oxford.
