Héctor Alfredo Moreno Herrera (born 17 January 1988) is a Mexican professional footballer who plays as a centre-back for Liga MX club Monterrey.

Héctor Moreno joined Club Universidad Nacional's youth system in 2003 at age 15, and made his way into the first team after winning the FIFA U-17 World Championship with Mexico in 2005.

Moreno made his professional debut during the Clausura 2006 tournament, coming on as an 88th-minute substitute for Gerardo Galindo in the 1–0 victory over Santos Laguna on 22 January.

[14] On 22 June 2011, it was announced Moreno would transfer to Spanish La Liga club Espanyol on a five-year contract for an undisclosed fee.

[19] Prior to the start of the 2014–15 season, it was announced Moreno would be out of action for up to six months due to a broken left tibia he suffered while playing for Mexico at the 2014 FIFA World Cup, which would require surgery and rehabilitation.

[21] Moreno made his return after four months on 14 November in a friendly against Marseille, replacing Felipe Caicedo in the 68th minute in an eventual 2–1 win.

[22] Moreno made his official return with Espanyol on 2 December, coming off the bench to replace Álvaro in the 73rd minute in the 2–0 victory over Alavés in the first leg of the round of 32 of the Copa del Rey.

Three days later, during PSV's opening 2015–16 UEFA Champions League match against Manchester United, Moreno broke the leg of Luke Shaw as the result of a two-footed challenge.

[27] A week later, he scored his first double as PSV defeated Twente 4–2 with assists provided by fellow Mexico national teammate, Andrés Guardado.

[28][29] On 8 May, Moreno played all 90 minutes in PSV's defeat of PEC Zwolle 3–1 on the final matchday to be crowned 2015–16 Eredivisie champions.

The following season, Moreno played in 39 matches across all competitions, and scored seven goals, a career-high tally, though PSV failed to defend the league as they finished in third place.

[33] On 15 February, he made his competitive debut for La Real against Red Bull Salzburg in the Europa League, playing 76 minutes in the team's 2–2 draw.

During midweek training, however, Moreno suffered a grade 1 injury to his internal obturator, meaning he would be ruled out for an undisclosed period of time.

Moreno was called up by José Manuel de la Torre to be part of the national team that won the 2011 CONCACAF Gold Cup.

[46] On 12 June 2012, Moreno scored the winning goal for Mexico in a 2–1 game over El Salvador in a 2014 World Cup qualifying match, the first of his career.

[50] On 29 June, in the round of 16 match against the Netherlands, Moreno suffered a fractured tibia after a collision with Dutch striker Arjen Robben inside his own penalty area.

On 1 July, the Mexican Football Federation announced Moreno would be ruled out of the upcoming 2015 CONCACAF Gold Cup tournament after a successful surgery on his right foot, which stemmed from complications related to a procedure he underwent six years prior following an injury to his fifth metatarsal.

[64] He would return to the field on 29 June in the quarter-final match against Costa Rica, coming in as an overtime substitute at the 106th minute and managing to score in the penalty shoot-out.

In October 2022, Moreno was named in Mexico's preliminary 31-man squad for the World Cup, and in November, was ultimately included in the final 26-man roster.

[73] Writing for Bleacher Report, Allan Jiang described him as being able to "read and quickly react in adverse situations", as well as having positional awareness.
