In July 2011, Trippier joined Championship club Burnley on a season-long loan as a replacement for the departing Tyrone Mears.
He made his debut for the Clarets in August 2011, a 2–2 home draw with Watford.
His first goal for the club came in September 2011, with a superb long-range free-kick against Milton Keynes Dons in a 2–1 win in the League Cup.
His first league goal came in December 2011, a 1–0 win over Brighton & Hove Albion at the Falmer Stadium, with a powerful shot from the edge of the box.
In December 2011, after impressing during his loan, Trippier was nominated for the Championship Player of the Month award.
On 2 January 2012, he received his first professional red card for picking up two bookings in a 2–1 defeat to Leeds United.
A day later, Burnley signed Trippier on a permanent deal for an undisclosed fee, signing a three-and-a-half-year contract.
In January 2012 he scored his second goal for the club, scoring from range in a 2–0 win away to Middlesbrough.
In March 2012, he scored the first in a 5–1 rout against Portsmouth at Fratton Park.
He played in all 46 league games in his first season as the club finished in mid-table, going on to win the Burnley Player of the Year award.

Trippier again went on to impress in his second season with the club being a virtual ever-present as he was named in the Championship PFA Team of the Year for 2012–13.
In August 2013, he scored a free-kick in a 2–0 win over Preston North End in the League Cup.
In January 2014, he sealed a 3–2 win over Huddersfield Town with a late goal.
He was again named in the Championship PFA Team of the Year for consecutive seasons as Burnley finished runners-up and gained promotion to the Premier League.
In May 2014, he signed a new improved three-year contract until 2017 after reported interest from Arsenal.
