篮球服是篮球球员所穿的制服。 篮球服背面有球员的号码和姓氏(或名字)，通常还会搭配短裤和运动鞋。在队伍中,球员会穿上代表球队颜色的球衣。主场队伍通常会穿浅色的球衣，客场队伍通常会穿深色的球衣。
不同的篮球联赛对于场上的球衣有不同的规范。在篮球早期发展阶段中，球员可以穿着任何类型的运动服。但在20世纪初期，特殊的运动服已经被制造出来并贩售给篮球员。球衣的风格、剪裁还有合身程度在后来的几十年中不断改进，而改进的方向大抵以当时的流行为主。
最早，篮球服装并没有被规范，而是有各式各样的种类，从田径服到美式足球服都有人穿着。The first official basketball uniforms, as displayed in the Spalding catalog of 1901, featured three types of pants: knee-length padded pants, similar to those worn for playing football, as well as shorter pants and knee-length tights. There were two types of suggested jersey, a quarter-length sleeve and a sleeveless version.
The long pants later evolved into medium-length shorts in the 1920s, and by the 1930s, the material used for jerseys changed from heavy wool to the lighter polyester and nylon. In the 1970s and 80s, uniforms became tighter-fitting and shorts were shorter, consistent with the overall fashion trends of these two decades. At this time, women's basketball uniforms transitioned from longer-sleeved uniforms to tank-top style jerseys similar to men's basketball uniforms, which more explicitly showed off players' muscle tone.
In 1984, Michael Jordan asked for longer shorts and helped popularize the move away from tight, short shorts toward the longer, baggier shorts worn by basketball players today. Throughout the 1990s, basketball uniforms fell under the influence of hip hop culture, with shorts becoming longer and looser-fitting, team colors brighter, and designs more flashy and suggestive of rappers' bling. At the turn of the 21st century, basketball uniforms became even more oversized and loose-fitting; the arm holes in women's basketball jerseys remained smaller than men's, but were wide enough to reveal the players' sports bras.
For the Christmas Day games of 2013, the NBA and its apparel partner Adidas introduced a newly designed sleeved jersey with large team and NBA logos on the front. Marketers for the new uniforms realized that fans were unwilling to wear sleeveless jerseys in their day-to-day life and hoped the new sleeved jerseys would be more popular for everyday wear. However, it was also a "not-so-well-kept secret that the NBA wanted to implement jersey ads in the years following the introduction of sleeved jerseys" as the "sleeves allow more space for potential partners to add their corporate logos to jerseys" like association football (soccer). After the league deal with Adidas expired and Nike signed on as the new apparel partner, the sleeved jersey did not continue.
The sleeved jersey was controversial among players. LeBron James famously ripped the sleeves off during a prime time game against the New York Knicks in 2015, but in the 2016 NBA Finals James convinced his teammates to wear the sleeved jerseys in Game 5 and again in the title-clinching Game 7.
In 1903, a special basketball shoe with suction cups to prevent slippage was added to the official basketball uniform demonstrated in the Spalding catalog. Over the decades, different shoe brands and styles were popular as basketball shoes: Chuck Taylor All-Stars and Keds in the 1960s and 70s; Adidas and Nike leather high-tops in the late 1970s and 80s; and Air Jordans in the 1990s.
In the 1970s, Slick Watts and Bill Walton began to wear headbands, which soon became popular with other players. Rick Barry popularized wrist-bands, and other players soon created variations, such as bands that covered their forearms or biceps. These were used to wipe off sweat, or simply worn as fashion statements.
在职业篮球或正式比赛中，主场队伍通常会穿着比客场队伍更浅色的球衣。
在NBA中，球裤裤缘不能超过膝盖以上一英尺处，而且球衣底下不能穿着T-shirts；而美国大学篮球的规定就比较宽松。许多NBA与WNBA在球衣上有着赞助商的广告标志。
Uniforms are made of wicking material designed to absorb sweat and ensure that it evaporates faster. They are the product of a four-year study researching professional basketball players, who identified the need for fewer seams, lighter weight, and faster drying and cooling in their jerseys.
The main difference between U.S. basketball uniforms and those of other countries is the appearance of sponsorship iconography; European basketball uniforms are often covered in the logos of their sponsors (similar to association football), while the U.S. uniforms (like other major pro sports) feature the team wordmark/logo front and center.
For the 2017-18 season, some U.S. teams have started putting sponsorship logos on their jerseys on the upper left of the jersey which is a maximum of 2.5 inches by 2.5 inches.
