# List of Ireland Twenty20 International cricket records

A Twenty20 International (T20I) is a form of cricket, played between two of the international members of the International Cricket Council (ICC), in which each team faces a maximum of twenty overs. The matches have top-class status and are the highest T20 standard. The game is played under the rules of Twenty20 cricket. The first Twenty20 International match between two men's sides was played on 17 February 2005, involving Australia and New Zealand. Wisden Cricketers' Almanack reported that "neither side took the game especially seriously", and it was noted by ESPNcricinfo that but for a large score for Ricky Ponting, "the concept would have shuddered". However, Ponting himself said "if it does become an international game then I'm sure the novelty won't be there all the time". This is a list of Ireland Cricket team's Twenty20 International records. It is based on the List of Twenty20 International records, but concentrates solely on records dealing with the Irishmen cricket team. Ireland played its first Twenty20 game against Bermuda in August 2008, and these records date from that game.

### Wicket-keeping records

The wicket-keeper is a specialist fielder who stands behind the stumps being guarded by the batsman on strike and is the only member of the fielding side allowed to wear gloves and leg pads.

#### Most career dismissals

A wicket-keeper can be credited with the dismissal of a batsman in two ways, caught or stumped. A fair catch is taken when the ball is caught fully within the field of play without it bouncing after the ball has touched the striker's bat or glove holding the bat, Laws 5.6.2.2 and 5.6.2.3 state that the hand or the glove holding the bat shall be regarded as the ball striking or touching the bat while a stumping occurs when the wicket-keeper puts down the wicket while the batsman is out of his ground and not attempting a run. MS Dhoni heads the all-time list of taking most dismissals in T20Is as a designated wicket-keeper. Gary Wilson is the leading Irish wicket-keeper on this list.

## Partnership records

In cricket, two batsmen are always present at the crease batting together in a partnership. This partnership will continue until one of them is dismissed, retires or the innings comes to a close.

### Highest partnerships by wicket

A wicket partnership describes the number of runs scored before each wicket falls. The first wicket partnership is between the opening batsmen and continues until the first wicket falls. The second wicket partnership then commences between the not out batsman and the number three batsman. This partnership continues until the second wicket falls. The third wicket partnership then commences between the not out batsman and the new batsman. This continues down to the tenth wicket partnership. When the tenth wicket has fallen, there is no batsman left to partner so the innings is closed.
