Mr Diamond is one of 25 people named on the list, which was lodged at the High Court by lawyers involved in a case relating to the manipulation of the London Interbank Offered Rate (Libor).
Former Barclays Bank boss Bob Diamond appears on a "short list" of names featured in litigation related to the rigging of a lending rate, legal documentation shows.
The list was released by court officials following a ruling by a High Court judge earlier this week.
Mr Diamond resigned as Barclays' chief executive in July 2012 in the wake of the rate-rigging scandal. He stepped down after Barclays was fined £290 million by UK and US regulators for manipulating Libor, the rate at which banks lend to each other.
Barclays says those named on the list had been "referenced" in Libor settlements not necessarily implicated or involved in wrongdoing, following regulators' investigations.
The bank says some people were referenced only as part of the "factual narratives". A spokesman said: "The fact that someone's documents were reviewed by the bank during its review of millions of documents does not mean that such a person was involved in any wrongdoing."
Mr Diamond had asked judge Mr Justice Flaux to keep his identity secret during preliminary hearings of the case before the High Court. He was one of scores of current and former Barclays' employees who wanted anonymity.
The application was dismissed by Mr Justice Flaux on Thursday. The "short list" of 25 also included the name of another former Barclays' senior executive, Jerry del Missier. Mr del Missier had also unsuccessfully asked for anonymity.
Several firms are airing grievances against Barclays in litigation which Mr Justice Flaux has described as a test case.
Bosses at companies which run care homes sued after claiming that Barclays sold financial products without warning that the inter-bank lending rate on which they were based was likely to have been "undermined" by manipulation. Barclays disputes the companies' allegations. Bank bosses say they do not believe that "any aspect of the case has merit".
