Match ends, Crystal Palace 1, Norwich City 0.
Crystal Palace boosted their top-flight survival hopes with victory over fellow strugglers Norwich, recording their first Premier League win of 2016.
Jason Puncheon scored his first goal of the season, cutting in from the left to score from 20 yards and lift Palace 10 points above the relegation zone.
Norwich will point to a penalty appeal when Matt Jarvis was barged over, but they had few clear-cut chances.
They lie four points above 18th-placed Sunderland, who have two games in hand.
The Canaries claimed a late win over Newcastle last weekend but, with 16th-placed Palace increasing the gap between the teams to six points, Norwich's home game against Sunderland next Saturday could prove crucial.
After Aston Villa neared relegation and Newcastle's defeat at Southampton, Palace now have a sizeable gap and another point should be enough to ensure survival.
Emotional Puncheon ends barren run
Having missed what he described as a "sitter" in the first half when he sliced a chance wide from 12 yards, Puncheon appeared to be in tears after his game-winning goal which meant Palace became the final team from England's top four divisions to win a league game this year.
He was later withdrawn as Palace hung on, but a first goal since May 2015 earned a first Palace win since 19 December, a time when they appeared to be pushing for a European place.
Their barren run since has included six straight home defeats but having earned a point at West Ham last weekend, there were signs that Alan Pardew's side were beginning to turn their form around.
The returning Dwight Gayle and Yohan Cabaye added pace and poise to Palace's play, but despite a succession of crosses, the hosts could not find a killer blow.
That changed when Puncheon scored a goal all of his own making to send waves of relief around Selhurst Park at the final whistle.
It also means that they could secured their Premier League safety before the FA Cup semi-final against Watford on 24 April, although they face Everton, Arsenal and Manchester United before then.
Norwich penalty appeal waved away
Norwich were the form team coming into this game, buoyed by two wins and a draw in their last three games, including their injury-time triumph against Newcastle.
In an edgy first half, they were on equal footing with the hosts as neither side threatened a breakthrough.
Palace keeper Wayne Hennessey had some nervous moments but the biggest talking point came when Norwich's Jarvis appeared to be barged over by Damien Delaney. However, referee Michael Oliver waved away the visitors' appeals.
The Canaries did increase their intensity once Palace went ahead and Ryan Bennett, who was solid in defence, had a volley well saved by Hennessey.
But Palace stood firm in the face of late pressure, despite Norwich keeper John Ruddy joining the attack from set-pieces.
Man of the match: Pape Soure
Crystal Palace boss Alan Pardew: "I was as nervous today as I have ever been in football. Sometimes the media can keep drilling it into you and in the end you are carrying that burden. I wanted to calm them down at half-time and they delivered for me.
"It was a robust challenge from Damien Delaney, to say the least. We had the best referee in the Premier League and he didn't say it was a penalty so I'll go with that.
"We are four points from mid-table and that is where we should be. If we can finish as high as we can then we can still get 11th. That's what we want to hunt down."
Norwich manager Alex Neil: "It was down to fine margins - there wasn't much in the game. You could see what was at stake for both sides and there weren't many clear cut chances for either side.
"Matt Jarvis was adamant at half-time that it was a penalty but it was difficult for me to see.
"I wouldn't put [the performance] down to nerves, it was just that nobody wants to make a mistake. You are just hoping to make the breakthrough first."
