Minister for Sport Shane Ross has announced Hockey Ireland will receive €500,000 of the €1.5m funding he announced at the homecoming of the women's hockey team.
The money will go to both the women's and men's teams.
Mr Ross said the fund will be spread across 17 organisations and is a separate fund to a €1.5m one confirmed in July.
He also revealed that Horse Sport Ireland will get €175,000, the Olympic Council of Ireland €175,000 and the Paralympics €100,000.
He said the money must be spent this year and described the funding as a "prompt respond to great success".
Ross said: "We have seen some truly extraordinary achievements over the past few weeks, with medal success for our Women's Hockey Team, as well as Irish rowers, sprinters, para-cyclists and gymnasts.
"Recognising the success of our sportsmen and women, who do so much to inspire Irish children and young people, I am delighted to announce this additional funding for high performance programmes across a range of sports.
"As I indicated previously, a significant proportion - some €500,000 - of this funding is being allocated to Hockey Ireland and I have no doubt that they will continue to build upon their remarkable successes of recent years.
"I would also like to highlight the consistently excellent performances of the O'Donovan brothers and I am pleased to be able to announce an additional allocation of capital funding to provide our rowers and sailors with the boats and equipment they need to compete at the highest level.
"I am committed to ensuring that Team Ireland will have every possible support on the road to Tokyo 2020 and I am confident that we will be able to provide further increased support in 2019 and 2020."
