Team GB’s former captain Kate, 36, was awarded an OBE, while partner Helen, 35, received an MBE as they were recognised for their outstanding careers.
Kate led the women’s team of rank outsiders to a sensational gold medal triumph at Rio 2016 last year.
The couple played key roles in securing victory in the final against the Netherlands after a dramatic penalty shoot out.
Kate, who has now retired from the game, told how she was warmly congratulated by Prince Charles when he awarded her gong and told her he used to play a bit of hockey himself when he was a schoolboy.
She said: “I told him I am too old to play in the National League now and he said ‘You’re never too old’. He was very charming.”
Kate said it was “really special” to be sharing the day with her wife and team-mate.
She said: “When I was at school and thinking of what I might be one day, this was nowhere near my radar.
Kate Richardson-Walsh, right, and wife Helen said it was the icing on the cake to be honoured
“I wanted to be a PE teacher and I would have been quite happy with that but this is like being in a movie. It is quite bizarre. It is like what dreams are made of.
Even going into Buckingham Palace is amazing
“I think it does show that, with hard work and if you really go for it, these things can happen to you.
“It was also so special to have this opportunity and see my wife have this recognition after having stood with her on the podium in Rio.”
The patriotic couple married in a civil ceremony in 2013.
