Winning Streak is an Irish television game show that was produced for the National Lottery, and broadcast from 21 September 1990 to 21 March 2020 on RTÉ One.

Produced in RTE's Studio 1 at their Television Centre in Dublin, the series featured contestants qualified via National Lottery scratchcards, who received the chance to win cash and other prizes.

The 2008–09 series was retooled as Winning Streak: Dream Ticket, with new co-hosts Kathryn Thomas and Aidan Power.

Aidan Power stood down after the 2008–09 series due to his commitments to The Cafe and The All Ireland Talent Show.

Marty Whelan succeeded Aidan, co-hosting the 2009/10 series with Kathryn, which aired from 12 September 2009 until 29 May 2010.

Kathryn was later replaced with Geri Maye, who presented alongside Whelan until 2013, when Sinéad Kennedy assumed the role of co-host.

In February 2023, it was confirmed that the show had been cancelled, although RTÉ remained open to a potential reboot in the future.

During each episode, five contestants played a series of chance-based minigames in order to win cash and prizes.

Contestants were chosen from an on-air drawing of qualifying Winning Streak scratchcards from a tombola drum.

The specific games played varied across the programme's run, but each episode concluded with a competitive round (known in its final series as the "Wheel Reveal") to determine who would spin the big wheel for a chance at the programme's grand prize.

In 2001, Murphy left RTÉ to pursue other ventures, and retired from presenting Winning Streak after the 2000–01 series.

Also in this series, the "Phoneplay" game was introduced, where three home players (selected from players who entered using a code on the Winning Streak scratchcard were randomly selected to pick from one of three spaces; two contain cash prizes between €1,000 and €2,500, and the other contains the star prize of a new car.

From September to December 2003, three additional players were drawn from the tombola each week to qualify for a New Year's Eve special, Winning Streak: Millionaire, where 48 contestants competed to win a grand prize of €1,000,000 won by Therese, A total of €1,613,000 has been won.

For the 2004–05 series, the studio was updated to feature a touchscreen, which is now used for selected games (such as Treasure Ireland and the revived Goldmine).

One player was drawn each week to go through to a special week-long series over the Christmas period, Winning Streak: Winner Takes All.

From 31 December 2005—11 March 2006, Laura Woods served as guest presenter while Mooney hosted RTÉ's music competition You're a Star.
