As of 2020, which cricket bowler has the record for the most five-wicket hauls in an innings in Test cricket?

A five-wicket haul refers to a bowler taking five wickets in a single innings. Sri Lanka's Muttiah Muralitharan has taken the most five-wicket hauls in Test cricket with 67 throughout his career followed by Shane Warne achieving 37.

Deshabandu Muttiah Muralitharan (born 17 April 1972) held the number one spot in the International Cricket Council's player rankings for Test bowlers for a record period of 1,711 days spanning 214 Test matches. Muralitharan holds the world record for the most wickets in both Test and one-day cricket. He became the highest wicket-taker in Test cricket when he overtook the previous record-holder Shane Warne on 3 December 2007.

Muralitharan had previously held the record when he surpassed Courtney Walsh's 519 wickets in 2004, but he suffered a shoulder injury later that year and was overtaken by Warne. Muralitharan took the wicket of Gautam Gambhir on 5 February 2009 in Colombo to surpass Wasim Akram's ODI record of 502 wickets. He retired from Test cricket in 2010, registering his 800th and final wicket on 22 July 2010 from his final ball in his last Test match.
