The Hillsborough Stadium Disaster Inquiry report is the report of an inquiry which was overseen by Lord Justice Taylor, into the causes of the Hillsborough disaster in Sheffield, South Yorkshire, England, on 15 April 1989, as a result of which, at the time of the report, 95 Liverpool fans had died (a 96th fan died in 1993, and 97th in 2021). An interim report was published in August 1989, and the final report was published in January 1990.

The Taylor Report found that the main reason for the disaster was the failure of police control. It recommended that all major stadiums convert to an all-seater model, and that all ticketed spectators should have seats, as opposed to some or all being obliged to stand. The Football League in England and the Scottish Football League introduced regulations that required clubs in the highest divisions (top two divisions in the English system) to comply with this recommendation by August 1994.

The report stated that standing accommodation was not intrinsically unsafe, but the government, nonetheless, decided that no standing accommodation should be allowed.

Other recommendations of the Taylor Report included points on items such as the sale of alcohol within stadiums, crush barriers, fences (as many Liverpool fans had been crushed to death against the perimeter fencing at Hillsborough), turnstiles, ticket prices and other stadium items.

After the Hillsborough disaster, Lord Justice Taylor was appointed to conduct an inquiry into the events. The Taylor Inquiry sat for a total of 31 days and published two reports: an interim report which laid out the events of the day and immediate conclusions, and the final report which outlined general recommendations on football ground safety. This became known as the Taylor Report.

Taylor concluded that "policing on 15 April broke down" and "although there were other causes, the main reason for the disaster was the failure of police control." Attention was focused on the decision to open the secondary gates; moreover, the kick-off should have been delayed, as had been done at other venues and matches.

Sheffield Wednesday were criticised for the inadequate number of turnstiles at the Leppings Lane end and the poor quality of the crush barriers on the terraces, "respects in which failure by the Club contributed to this disaster."

Taylor found there was "no provision" for controlling the entry of spectators into the turnstile area. Questioned why more action had not been taken to screen individuals and improve the flow of supporters approaching the stadium from the west "where the turnstile area was so small and awkwardly laid out", senior police officers responded that policy and practice had been no different from in the past, and they had no reason to anticipate problems as earlier events had proceeded without major incident. In fact, Taylor noted only two occasions when the entry at Leppings Lane had been the sole access to the north and west sides of the ground, at the 1987 and 1988 semi-finals, with evidence of congestion at both, but owing to good fortune and circumstance police policy "was not put to the same test and strain as a year later".
