2012年7月7日，马丁内斯以1100万美元的身价加盟葡萄牙足球超级联赛球队波尔图，违约金为4000万欧元。 8月11日， he played his first competitive match for the Portuguese team in the 2012 Supertaça Cândido de Oliveira against Académica de Coimbra, also scoring his first goal. He would score in the 90th minute which gave Porto their 19th victory of the tournament. He was named as the man of the match.
Martínez scored his first league goal on 25 August from the penalty spot against Vitória de Guimarães in the 80th minute with Porto winning the game 4–0. The second league goal came on 1 September against Olhanense with the game finishing 2–3 for Porto. In his next league match against Beira-Mar, he scored a bicycle kick from a chipped pass by fellow countryman James Rodríguez. In the fifth matchweek, Martínez avoided a 2–1 loss for Porto after scoring in the 90th minute in an away game against Rio Ave. Against rivals Sporting CP, he scored with a stunning back heel volley in an 2–0 win. During the third round of the 2012–13 UEFA Champions League group stage, Martínez scored his first goal in European competition thanks to an assist by James Rodríguez against Dynamo Kyiv. He scored again in the same match, which ended 3–2 to Porto. Martínez continued his goal streak in a 2–1 victory over Estoril, scoring one goal and assisting the other.
With 11 goals in 12 matches, he eclipsed the record of former Porto strikers Radamel Falcao, Lisandro López and Hulk. He became known as "Jackshow Martínez" in Portugal, which was coined by journalist João Ruela. In the same day, after he scored two more goals in a 5–0 victory against Marítimo, he made the front page in every sports-related newspaper in Portugal. His goal-scoring performances in domestic competitions also resulted in him being named the SJPF Player of the Month for the months of October and November.
In the final round of the year's Champions League group stage, Martínez scored a goal against Paris Saint-Germain in a 2–1 defeat. Despite the loss, Porto advanced to the next round as the second-placed club in their group. Against Moreirense, he scored a goal following an assist from James Rodríguez.
In the beginning of the second half of the league, Martínez scored a header in a 1–0 victory over Nacional. He then played in O Clássico against rivals Benfica, where he scored in a 2–2 draw. In the delayed match against Vitória de Setúbal, Martínez scored a double, one via the penalty spot. In his next match, he sealed a 5–0 victory with a 90th minute goal against Gil Vicente. He scored a hat-trick against Vitória de Guimarães, which included two headers, making it his first hat-trick for Porto. At the time, he had scored 18 goals in 17 matches in the Primeira Liga. Jackson continued his goal-scoring streak after netting the equaliser in a 1–1 draw with Olhanense, followed up with another against Beira-Mar one week later. Martínez added two more goals against Rio Ave, including a penalty and a volley following a cross by James Rodríguez. For his prolific scoring pace, Martínez was named the February SJPF Player of the Month.
Martínez made his Taça da Liga debut in the 2012–13 Taça da Liga semi-finals against Rio Ave, where he failed to score a goal. Regardless, Porto won the match 4–0 and advanced to the finals. He ended his goal drought in a 0–3 away victory over Moreirense, where he scored a brace.
In the final match of the league season against Paços de Ferreira, Martínez sealed the 2–0 victory after scoring the second goal and assuring Porto's third consecutive league title, finishing just one point ahead of rivals Benfica, who had also won their final match. The goal marked his 26th goal in the league, securing him top goal-scoring honours. With winning the Portuguese SuperCup earlier in the season, finishing as top goal scorer and winning the league title (in just his debut season in Europe), Martínez had a successful season debut.
ESPN noted Martínez as one of the best signings for the 2012–13 season following his seasonal European debut.
