Samuel William Johnson (born 1 December 1992) is an English professional footballer who plays as a goalkeeper for National League club Halifax Town.

[4] Johnson turned professional at Port Vale in April 2011 and played on loan at non-League Stafford Rangers later in the year.

Born in Newcastle-under-Lyme, Staffordshire,[3] Johnson started his career in the youth system at local club Stoke City before being released at age 14.

[5] He quickly joined the city's other local professional club – Port Vale, after youth-team coach Mark Grew spotted his potential.

[5] Johnson was not fazed by the prospect of a first-team debut, Grew comparing him to Paul Musselwhite in his unflappable, rather laid-back personality.

[7] He made his debut in a 5–4 defeat by Hednesford Town at Keys Park on 29 August, though manager Greg Clowes refused to blame Johnson for the five goals conceded.

After Neal picked up a groin strain, manager Micky Adams had little recourse but to hand Johnson his debut on 9 October, in a Football League Trophy match with Walsall at the Bescot Stadium.

[18] Johnson made his debut in the Football League on 30 November 2013, again away to Walsall, and impressed after keeping a clean sheet in a 2–0 victory.

After the match, Adams confirmed Johnson would keep goal in the absence of Chris Neal, who had injured his wrist in training.

He did, though play at Wembley Stadium in the 2016 FA Trophy final and kept a clean sheet as Halifax beat Grimsby Town 1–0.

[41] He made 41 appearances in the 2019–20 season, which was permanently suspended on 26 March due to the COVID-19 pandemic in England, with Halifax in the play-offs in sixth-place.

[44][45] Speaking shortly after playing his 200th game for Halifax, Johnson said that he thought he had his weakest season for the club but had benefited from being tutored by goalkeeping coach Paul Oakes.

[47] He featured 51 times in the 2021–22 campaign, keeping 19 clean sheets to help Pete Wild's side to qualify for the play-offs with a fourth-place finish.

[50][51] He was an ever-present again in the 2022–23 campaign, keeping three clean sheets and being the victorious goalkeeper in three penalty shoot-out wins en route to the club's entirely away-from-home journey to the 2023 FA Trophy final.
